<human>: Give me a shortened version of the text

I'm 24. Almost three years ago I had a serious "relationship". It was with a girl I knew from school, and for about 8 months we had this fling where we'd hook up most weekends and hang out most every day. She was my ideal partner in life, and I totally loved her.

I wanted our thing to be "official" for a long time, but she wouldn't do it. I found out that was because the whole time we were together, she was hooking up with other guys semi-regularly. I got pretty upset with her, and she blew me off. She said it was stupid of me to think that I meant anything more to her than just a hookup, even though we were great (best?) friends and she had even met my parents a few times.

I told her that I thought she was a terrible human being, and we never talked again. I got really depressed. It demolished our group of friends, which most people blamed on me. I sent messages trying mend things in a way that at least we could be okay and not make our friends pick sides, but she refused to talk while trying to sabotage my friendships. I think the worst feeling possible is meaning nothing to the person who meant everything to you.

Since then, I haven't allowed myself to get close to anyone. I never want to feel that way again. I've slept with a lot of girls because that was the bro advice to get over it, but it's only a temporary good feeling. After a few times with the same girl I'll cut things off, always before they or I can really develop any sort of attachment. I've never slept with anyone who's liked me, only random hookups. I wouldn't want to do that to anyone.

So here I am, at a point in life where many of my friends are getting engaged or are at least in long term relationships, and I don't know what to do. I feel like I'm going to turn 35 and end up marrying whatever is available just because I feel like I have to before I get too old. Hope someone out there can give me some good advice, and it's nice to have a place where I can talk about this. thanks
<bot>: happiest relationship I've had was completely one-sided and ended horribly, and now I'm afraid/jaded when it comes to relationships.
