I have been dating this guy for a year, and I care about him a lot but I don’t want to be with him. It’s kind of one of those “our parents wanted us to be together” things. But I’m in love with my ex.
My ex and I broke up 3 years ago but have been sneaking around and seeing each other in private.. is it wrong of me??? What should I do? Because now my ex is talking to me about this great new girl he met who he likes, and what not. I just wish I could be with him.. but I can’t break up with my current boyfriend, and now I feel like my ex is using me for sex. I’m stuck and I feel like a horrible person.

You feel guilty, because what you have been doing is wrong. You can break up with this guy and should right away. He needs to be able to move on and find someone who actually cares enough about him to tell him there is a issue before they start cheating on him.
I wouldn’t go back to the ex. You need some time ALONE to figure out why you are co-dependant on the ex who cares so little for you that he uses you for side action while dating other girls. He’s no longer into you.
Seek counceling or you may turn into a life time cheater. Also, while it’s good to have your parents approve of your dating life, they don’t have to live with the guy. If you are grown up enough to have sex, then you are grown up enough to tell them this is your life and then go live it. It’s healthy to have those boundaries with your parents as a adult and you certainly need them right now.
