So, my aunt and my boyfriends dad are going to get married. He knew this when we started dating around four months ago. Now, he is saying it isn't going to work and he doesn't know what he wants. I have been through this four times, not under the same circumstance, but of him not knowing if he wants to be with me. So, he came to me today to say that he thinks we could never go forward in our relationship, although I do, but he doesn't know what he wants. Please help me on a way to either let him go, or get him to want to be with me, and see we can go forward.

If you've gone through this FOUR times in FOUR months, then no it's not going to work.

No contact is best!

At least for a while. Plus seeing as you are family now, it might be easier to try a friendship later on, instead of a relationship.

Yes if it is that off/on then there is issues just to start with, have no idea what the cousin thing has to do about it ( since it does not have anything to do with it)

Well Chuck, I think that it does have something to do with it. Because she will have to see him every once in a while at family functions and such.

You can't make someone be with you when they don't so when this happens you move on and be glad no more time was wasted.
