John,

Asking her mother is one approach but I believe you continue to dis-empower your gf by taking responsibility for finding a place for her and her children. She can play a helpless victim but seeing if her own mother will take her is her responsibility.

You say you want to be alone and want to date again. My take is that you need to work on yourself and take care of your children. You have gone from one relationship to another. My belief is that you need to learn to be by yourself for a while. Happiness is not another woman. Take stock on your behaviors and reflect. Get some therapy to understand yourself better.
