How can I build confidence after proposal?
Some background: I am 30 years old. Have been divorced for 4 years, and in a relationship with an absolutely wonderful 40-year-old Englishman that I love very much for the past 3 years. It's long-distance, he's in London and I'm in New York, but we see each other 4 or 5 times a year and communicate a lot via text, email, phone and Skype. I am an anxious person in general, and have been all of my life. He is very understanding of this. We are both busy in our professional lives and have school-age kids, but make time to talk every day, even if it's just a few quick texts or an emailed pic of something from our day.
Recently, he called me up unexpectedly and proposed. We are seeing each other this fall and getting "physically" engaged, like, with a ring and such, and have already started making some general wedding plans. I was shocked, and thrilled, but every since then, I have been extremely, extremely anxious.
I can't pinpoint exactly why, but this to marry this man would be a literal dream come true, and I can't help but feel that it's all some sort of cruel joke being played by the universe. I don't see how I can be deserving of such a wonderful opportunity, and it's turning me into a lunatic. There were trust issues with my ex-husband, which I am now projecting into my 'new' gentleman. All of a sudden, I am acting like a clingy highschooler, analyzing his texts for hidden meaning and freaking out if his email doesn't contain a smiley face. Yes, really. He has always been honest yet gentle with me-- if he is in a bad mood or having a busy day, he will let me know and we will make arrangements to Skype the next day, for example-- and now I find myself constantly wondering if he is just waiting for the right time to dump me.
I don't want to be like this, it's driving me crazy. I also don't want to be needing constant reassurance from him-- what kind of message would it send if all of a sudden I don't believe he loves me or actually wants to marry me? I don't want to be that person who needs to hear "I love you" 45 times a day and still doesn't believe it. How can I build confidence so that I can enter this marriage in a good state of mind, and actually be happy that I've finally found the man of my dreams?
