you were right to wait.

wait longer until they have broken up and then you can start dating him properly.

You are being smart. I wouldn't because if goes out with you right after breaking up with a girl you will be a rebound and rebound relationships have a 90% chance of not working out. Go with your gut instincts you are making the right choice and don't need anybody's advice on here because you are being very logically. If you do like him though and he does break up you can be there for him and tell him that in a few months if you are both single then you would like to date him. But for now he should take some time to heal.

Yeah ur right in not dating him. U don't want to be his rebound. How do u know after a few weeks after breaking up with her he might regret it and think about her again? So u definitely should tell him he needs to break up first and give himself time to move on. In the mean time, if ur still interested in him but don't want to date him just yet, tease him a little. Make him want u more than he does now by being awesome.

The man usually makes the first move. Even if she’s interested in you, the most she’s likely to do is to stand near you or make eye contact a couple times to encourage you to approach her. Read here https://tr.im/J3OGy

Once you see her, don’t hesitate. 10 minutes from now she might not be there or another guy might have beaten you to the punch. Plus, women can tell when you’re working up the courage to approach. Shyness might be endearing in movies and romance novels, but it doesn’t work in the real world. Approach right away, even if you don’t know what you’re going to say

you don't have to respond. You told him how you felt.

Anyone who sends flirting messages to another girl when they already have a girlfriend is 1) not very faithful to the current gf and doesn't have the balls to break up with her, and 2) is looking for sex or someone to play around with, not a date and not a serious relationship.

Just ignore him.

If you go out with him you ARE coming between him and his girlfriend, and could actually break them up. Something else to consider is if he is so ready to go out with you, what happens if you become a couple and he suddenly finds some other girl he likes?

Woah this guy needs to grow up and figure out what he wants. If I were you, I would stay away from a guy who doesn't even have the guts to tell his current girlfriend it's over before he starts messing with other girls. I can only imagine he wouldn't hesitate to do the same if you were his girlfriend.
