She says she's very bad at replying?

It’s hard to meet and really get to know a strong woman online. It's just too easy for someone to pretend that they're someone they're not. Use dating to find out what he is really like. Pay special attention to how she reacts when she doesn't get her way or something goes wrong.

May I suggest that the first question to ask yourself when considering whether or not to date someone is, “Is this person a strong person?” If they’re not, no matter how much you like them, how much they like you, or how “cute” or “hot” they are, - please don’t date them. A strong person has good character (honesty, integrity, trustworthiness), displays a positive attitude (cheerful, caring, friendly, forgiving, helpful, and respectful), fulfills their responsibilities (for handling people who are pains in a positive way, for always trying to make a good choice, for taking care of themselves, for serving others), gives their best effort, and demonstrates self-control (of their body, anger, mouth and money).

My suggestion is that you put in the effort necessary to become a strong person (if you’re not already), break things off with this girl in a kind way unless she’s a strong person who you can date in person, and eventually look for this type of girl (otherwise you’re setting yourself up for a broken heart). Unfortunately this type of woman is difficult to find - but save yourself the heartache and don’t settle for less.

(Please remember that you eventually want a 50 or 60 year marriage - not a 5 or 10 year marriage.)

Hope this helps!

PS Here are "21 tips that could help you to attract a strong person" from the book True Love Lasts:

1. Take the time and put in the effort to become a strong person yourself (this is the most important tip)

2. Put yourself in as many situations as possible that will allow you to potentially come in contact with other strong people - community service organizations, the library, high school or college clubs, the “Y” or other workout facilities, religious book studies, coffee shops, non-alcoholic parties, bookstores, concerts (wear a good pair of earplugs to protect your ears from permanent hearing loss), co-ed recreational athletic teams, community service projects, mission trips, volunteer service, etc. Try to get to know other people as much as possible without dating

3. Be cheerful, approachable, and friendly - smile regularly to put others at ease (let people see your positive attitude)

4. Take a real interest in getting to know others. Ask people an open-ended question about themselves in order to get them talking. Share things related to what’s been said as needed to keep the conversation going. Then ask them another question

5. Be polite and kind to everyone - even to people who you don’t like or enjoy being around

6. If you decide to not accept a request for a date, do it in a kind way (being rude isn’t a good choice and it doesn’t help you - word about it will get out and you’ll become less approachable)

7. Be confident about yourself - if you’re trying to become a stronger person each day, you already have a lot going for you

8. Be humble - don’t act like you’re Miss Charming or you’re Mr. Wonderful

9. Don’t be concerned about whether or not someone likes you

10. Have the attitude that if someone doesn’t like you - they don’t really know you

11. Take care of yourself by getting enough sleep (at least nine hours for teens, at least seven hours for adults according to the experts), exercising regularly (if approved by your doctor), and eating a healthy diet

12. Develop a good sense of humor - including the ability to laugh at your own mistakes

13. Be known as a hard worker

14. Dress well and dress modestly at the same time (wearing seductive clothing doesn’t attract another strong person)

15. Pay attention to your appearance, but don’t obsess over it (remember that strong people are attracted to other strong people, they’re not too concerned about looks - because they realize that looks fade with age). If you use makeup, make sure it’s not excessive. Use perfumes and colognes sparingly - if at all

16. Truly care about other people

17. Stay in close communication with real friends who can help you through the ups and downs of life and hold you accountable

18. Be patient - real friends can help you with this

19. Persevere - please remember that almost nothing worthwhile is quick and easy. Please don’t settle for dating a weak person

20. Don’t take it personally if someone doesn’t want to date you

21. Don’t act desperate for a date

Get over your emotional need to have someone text you every 5 minutes. 

Met her on line and communicate by text. Why not meet up in person? Until you have face-to-face conversations, this isn't going to be much of a relationship. Expecting immediate makes you come across as a bit needy and desperate. 

If a new friend is a frequent texter, I make this request of that new friend: "If it CAN wait, please let it wait. I'd rather not get texts at all than get unnecessary texts." And I expect that new friend to honor my wishes in this matter, even if that new friend "isn't used to" exerting him/herself to distinguish between what is and what is not urgent. 

I'll give the new friend a few chances, tactfully (I hope) pointing out that urgent and important aren't the same thing, that "I'm anxious to tell you" isn't the same thing as the matter being time sensitive. But if the new friend continues to annoy me with frequent unwelcome texts I'll ask that new friend to not text me at all.

Is that what you're aiming for? This lady telling you to buzz off if you can't respect her preference to NOT engage in frequent texting? What you should do is get used to exerting a lot more consideration and self control instead of thoughtlessly demanding attention whenever you have some flimsy excuse to do so.
