First Love

Mine was only 4 years ago but I still think of him. He just recently stopped calling, and telling me he missed me, within the past year. We were together for a year and a half. You never really know what love like that is until you've lost it and gained its meaning. There's nothing I would have ever done differently. I broke up with him because he openly started dating other girls while we were together. The cheating started after only about 6 months of us being together. It took me a while to not take him back. But needless to say, I wasn't his first. He had been with two others before me. I love a good party and a good time but I can't even count how many girls he's been with since me. I hate to admit it but I was 'one of those girls'. He cheated on a lot of his girlfriends with me. After I finally officially broke it off, he began this spiral deep down. He's all about the parties and drugs now.

I worry about him a lot and I wish I could say something without him thinking I want him back.
He'll learn on his own.

I've had other relationships since him and I've gained some experience and learned a lot. I know I still have a while to go before I find 'Mr. Right'. I'm just not going to be one of those people who concentrate and devote all my time to finding him.

Does anyone still think of their 'first'?
Have any of you been cheated on by your 'first'?
