Catnapper said exactly what I was going to say. Imagine life without him. If you can handle that then there is your answer.

I've been with my boyfriend for over 7 years now and I've accepted that we will probably never get married and I'm fine with that. Other people around me do not seem to understand and are always asking both of us about it.
He's been married before and she ruined him. Pressured him into marriage and then ended up cheating on him. He feels he is too old to have children (he turned 50 in Feb) so I know that isn't going to ever happen either. I'm happy and can't imagine my life without him so I'm staying right where I am.

I wish you luck in whatever happens.
