I would think long and hard over this before you give him and ultimatum or start to call it quits. I think he has tried to be honest with you about his situation and the fact that it will cause problems with his ex etc and I think you should have a real good think about that. His situation does appear to be very different to yours. Some fathers do get a real bad time when they introduce their children to new girlfriends, partners etc and it affects the contact that they have with their children. Its not fair but sadly it happens. It is very different for the parent who the child/children live with the majority of the time as they don't have these restrictions put on them.

You have chosen to introduce your boyfriend to your children as you felt that it was an appropriate time for them and him. However I think that, unless proved otherwise you should show that same respect for your partner, in that he has assessed his situation and feels that it is not the right time at this moment to do the same.

I can understand that you are hurt by this. However, he is not saying never, just not at this time. Good luck with things.....sending you a hug x
