My boyfriend and I are fighting too much. Last night was getting really bad. Very bad. and the next day, I'm depressed and sad and I can't work or do anything.
I hate this situation.

We've been together for almost two years. He basically lives with me without paying a penny. He has two kids and lives with his mom when he has his kids.
He's 45 and I'm 41.

I really want to have kids and my time goes by quickly waiting for him.
I feel he's the only and last man that I can have child from.
But at the same time, he has tremendous of issues and problems. Credit problem, kids problems, riding an old car, not having a proper home for himself and his kids.

In the other hand, I own my house and I have a good job and I have no debt except my mortgage!

He has a good job, and make good money, but I don't think he's capable to make right decisions.

I'm so afraid of breaking up with him and ended up alone!

what should I do to change this situation?

Thanks
M
