You know what, if you can get alone, just be yourself. You have to have enough confidence in yourself to remember that you are the person she fell inlove with in the first place. Dont try to be someone else either. I think that when we say you have to be tough thats not to say change who you are, just know that she deserves to be loved but so do you. You are a good person too, and dont let anyone **** on you either, You know what i mean. Your feelings are just as important as hers, and she needs to know this. Do you think it could be a self esteem with her. I dont know how old you guys are but im guessing late twentys or early thirtys. I know myself i got married young and i was used to getting alot of attention from guys and my husband, He was always jealous. Then the kids came and then sometimes you feel like they got you where they want you. And sometimes you feel like you have to prove hey look other guys still want me. Just guessing. But i can remember feeling that way. Sometimes you get too comfortable and forget you still have to find a way to show you care. money, work, its like life is sometimes passing you by. I think it really normal thats why its called the 7 year itch.
