So my ex and I have been broken up for 2 years now. I have moved on and met other people, and yet stayed in the house we live in with him. He never leaves except for work... Tells others that he talkes to that I am his family and only friend... But now he is talking to this guy which sorta bothered me, and now they are sexually active which really bothers me... Could it be because up until now, we still hung out, I was the only person that he had and now it seems as if I am not important? He used to tell me everything whereas, now everything seems second information. It also pisses me off to see him do things with his new that he never wanted to do with me in the 4 years we were together. Things I always wanted to do as a friend and boyfriend. I thought I moved on... I am in a new relationship but see myself pushing him away because things are running in my mind. I feel as though I am loosing my friend my family... Even though we broke up we still live together and we still say we love each other ... We just weren't compatible in some areas that made us fight. Is it normal? I mean it's been 2 years... I feel lost...

There is really absolutely no reason why he should be acting so open "in love" with a new lover, in front of you like that. He doesn't have to act so boldly right in front of you. He's being disrespectful. Has he even taken into account the way that might make you feel? Doesn't he realize it can make you feel, awkward, and uncomfortable? I mean, hello. You are his ex for crying out loud. You both have memories. You both have a past. You both "had" love.
Despite what anyone says, there will always be some left over feelings for that person you once were "in love" with. Whether that flame is buried or not, when an ex is flaunting there new relationship infront of their former partner, it's gonna bring back some old feelings. The flame whether buried or not, will rise, because you will remember the past, and the memories that made you smile. You're bound to feel at least a little something. Especially if you guys were that close when you were together, "like family" they're probably gonna have a place in your heart for always.
Sure, he might have moved on completely, but maybe his new relationship is making you realize that you're not over him just yet, or maybe you feel slightly replaced. And him telling you he loves you all the time, is making the situation seem really wishy-washy too. Just tell him how you feel.
you need to be away for him for a while..
and for you to say i love you to each other makes it more difficult..
i know you treat him as a family and friend but do yourself a favor, stay away from him and when the time comes that you heal you wont feel these things anymore..
You have no right to interfere with his love life or to lay claim to him.
I said he didn't have the right to interfere.
If he wants to re-establish a claim on the ex, he needs to be up front about his feelings and say, "I want you back."
