Tomi, for your own sanity and ours. Find out : When he did time, What it was for exactly, How long it was for, Where did it happen.
You should be able to find past newspapers telling all of this.
Start locking your doors so he can't come and go.
If you need help doing things call a volunteer program, at least you'll be safe with them,
Remember
1. You are a Mature Married Lady w/ Children
2. He has a live in other
3. You DON"T really know anything about him, con-artist are very good liars
This one might make you mad at me but I give a damn about you
4. Stop acting like a school girl with a chrush, he's dangerous
