These things are difficult when children are involved, however, there was obviously a lack of commitment from the beginning. This man might have been separated when you started dating, but the fact that he was looking to seek out another person so close to when his marriage ended demonstrates he wasn’t completely tied to his first committment. He fathered a child with you and wasn’t even willing to commit to the family as a unit by marrying you. I understand some may have the attitude of “Why do we need a piece of paper to prove out committment?” well, why not?

Aside from the fact that he appears to be fickle (left his wife, jumped into something serious with you immediately and now after 6 year has cold feet), the bigger issue is that you stated you love him more than you love yourself. I understand that as women, we love hard and deep. You need to love yourself first and stay true to that love and committment you give yourself in order to expect respect and better treatment. There is nothing wrong with wanting a stable loving environment for your child and you, you deserve that and your brought your daughter into this world, wouldn’t you want her to see that she should expect respect out of her future relationships when she’s a woman going through life? Love the father of your child, wish him well, and give him space to figure out where this is going, but please don’t compromise the fact that you need respect, love, and untimately to trust him. Deleting you from his facebook account, and not responding to your attempts to communicate doesn’t show he’s trying too hard.

When you are ready, you will have to ask yourself some hard questions: What if he never intends to marry me? What do I want from this relationship and how long am I willing to wait? What’s best for my daughter? How does my daughter witnessing this relationship affect her in the long run? If my daughter were in my shoes, what would I tell her? (it gets harder) What if he never wants to get married? (harder) he pulled away from his wife, and found me, what if he has already found someone else?
Knowing what you are willing to put up with vice what you want will give you a clear picture of where you want to go. Please take this time to work on loving yourself, because if you don’t, how are you going to be able to put that love and respect into any other relationship if it doens’t begin with you?
Good luck and I really hope this works out for the best.
