I've been reading the weddong/ex thread and realised I'm stuck in a very similar situation.
Ten month relationship, live separately, I haven't met his kids, he's met mine briefly, i fit in with his schedule, he fits in with his ex's schedule. He has put off me meeting them because he's scared of things not working out.
I'm at the point where I want to see a proper future with him and he constantly procrastinates. I think he knows I love him too much to end things with him but I don't know how long is reasonable to wait for change.
