About 4 months ago I was dating one girl. It was all going great until I started to rely on her for me to be happy. If I texted her and she didn't respond within a few hours I'd feel restless. I wouldn't act on it and double text, but I was always uncomfortable and despite not acting, it influenced my next message after she did reply. I was always on edge and I hated feeling this way, even after I had already established that we were both seeing one another, constant kissing, etc. Eventually, I'd bring it up a bit more how I want to text her a little more, just to know that she's still alive, I asked for her to at least reply to me once every few hours so I know that she at least wants to talk to me, and it was needy and that's probably why she moved on to a new guy without telling me, and that's when I dropped it and moved on.

Recently, I connected with a new girl. Had sex on the first date, went on a few dates afterwards and it was all going great. Texting wasn't an issue here, I didn't care as much about it and nothing was going wrong, I had an almost full time job and college, and she had the same so our lack of texting was understandable. Our last date was garbage. Sex lasted all but two minutes, I asked her a very personal question, and I told her something very shitty about me in my past. Bad move guys, don't do it, I don't know why I did, even though she asked I shouldn't have. So eventually this one ended too. I told her that we probably aren't ready and that we should stop, but it was great knowing her. Said we'd see each other around, smiley faces, civil. Rare for me.

This was today.

I was almost devastated, even though our "relationship" had lasted all but 3 weeks. What helped? The fact that I got three numbers today. I didn't even DATE these three girls yet whose numbers I got, I just approached them while I was working and got three of their numbers. I texted one and she's replying well, and the other one is as well, and the third has already set up a date with me. I have options, I have three of them. If one doesn't work, I'll move to the next. I realize right now that I fall for every single girl I date because I let them come to me, and then I put them on a pedestal but the more options you have, the less the last girl will hurt when she leaves. Have options, guys. That is 100% the key to solving your issue with oneitis or whatever it is that you have. Text many girls at a time, because then when one doesn't reply, you won't give a flying fuck because the other 2-3 or more are replying. OPTIONS.

edit: Set up TWO dates. One of the girls ended up being really religious but wants to go on a date. I'm not into girls that are this religious, but she seems like a great person that'd be a good friend so I'm going for it.
