I can only imagine how upsetting this is. You thought you’d found a soul mate and a few ill-placed words seem to have fractured a promising relationship.
Finding love again as an older adult is very, very complicated. It is especially complicated when there are children involved. Yes, even adult children. They often have loyalty to their other parent. They often have opinions about the new person in their parent’s life. In addition, your boyfriend has a young child to still parent.
If that were not enough, your boyfriend was not married when he was married. He has a history of not committing to anyone. In order to have been with 300 women, he had to charm that many to be with him — in spite of the fact that he was married. I suspect that his wealth, as well as his charm, was seductive. Talking about meeting his kids and vacation plans may be part of a well-practiced line.
By declaring your feelings and using the marriage word seriously, you moved from being yet another daliance to a complication. Given his history, it doesn’t surprise me that he has pulled way back.
I’m so very sorry that you are disappointed. But from where I sit, you are fortunate to have found out what he’s really about before you got in deeper. I suggest you drop him and make yourself available to someone who knows how to really love only one person. You deserve to be more than number 301.
I wish you well.
