I have a very serious question,so I need some honest help.Ok I am married, but am not in love with my husband.To make a long story short.It feel like we just wanted to be with one another.At the time I had just broken up with my boyfriend of 3 years,and he had broken up with his girl.We knew if each for a long time,and had always had a crush on him.Anyways,we got married, but I am still in love with my ex!My husband and I fuss and fight a lot.We have even filed for divorce,but he stopped it.He wanted to work things out.So right now,we are trying to work on things.But I just cant give my all to him,because I dont deeply love him.I have feelings for him,but my love for my ex is even stronger.Ok we live in CO,but when we have a fight he,always wants to send me back to SC.I really am trying to make it work,because we are married.The smart choice would be for me to stay with my husband,because he is a better financial provider.My ex has my heart and soul.What should I do.Any advice is good.
