Confused

Married 22 years and divorced 2 years. My husband left but we still have not sold are house. He comes around alot and is very helpful but continues to bring up the past or blame me for what is. At times he acts like he wants me back but doesn't say it. Other times he tries to make me jealous. Its getting harder for me, not easier. I cant stand the crying, sleepless nights, constant thinking, lonliness, and more crying. How do I know what to do. Would it work agian or am I crazy for even thinking it.
