Getting over an ex

i spent a couple of years with a great person who was my significant other. he was my everything and we were really in love. at least i thought so.

he broke up with me, then moved on very quickly. in weeks he was already dating around & he was posting pictures of himself with his friends. i was suffering but he was very happy & satisfied with his life. this is the same guy i dedicated years of my life to. quit jobs to be with. rejected jobs that required relocations. all to be with him.

we were spending time together every day, every night. the best part of every morning was his face, his smile, his greetings when we would first see each other.

well since he was gone it has been years. we both grew up but only one of us really moved on. well, it wasnt me that moved on.

i still think about him every day. sometimes stalk his photos or his posts. looking through old texts, old photos, old letters. even some of his clothings. now it seems that there are talks of his engagement to a woman. not sure but its what mutual friends have told me.

it rips me apart just thinking about him being with someone else. does anyone else ever get that feeling? that we come across one significant other in life & if we lose them, that's it?

i need to get over this guy but that's easier said than done. even getting back to the dating game does little to help the situation. all i do is compare the people i meet with my ex. no one else comes close.

has anyone else here ever been in a similar situation before?
