My ex-girl friend mom died, now she say's she don't love me. What do I do, she pushs me away, then sometimes she prays with me, her brothers call me and told me to trust him and give her space, and her father was going to come to the house and live with her.

She is going to need love and support, during a very hard emotional times.

You need to be ready for anything and I mean anything... one day she could be with you, and the next day she may want to leave you... just make sure you are there for her in every possible way during this hard time...

She is an ex, but she needs your friendship and support, not a selfish ex. If you cannot give of yourself without being selfish, leave her alone.
