You are repressing yourself from getting over him/her and it sounds as though you have not fully come to terms with the split. Try talking this over with the person you have split with.
Fall in love with someone else
Either you lover is the best out there, or there is someone else on the side :-/
Yes.
The fear of infidelity.
You should find another lover.
You don't go there.
Ask around. Someone knows.
dating someone else ;D it always work ^_^
Ask him, or follow him.
because he still misses you or he hasn't found anyone else or he has found someone else but this person could be somone that you know or very close with.
no it usually is because they are seeing someone else or their scared of change.
I guess I'd have to answer that question back with another question: Why would you want a man back after he has walked out on you and your children and is seeing someone else?
