<human>: I've dated a lot of guys in college, a fair mix of good and bad. In the beginning I could "bounce back". I could walk away from a failed relationship because we had always ended on good terms (we mutually agreed it wasn't working). I could walk away and bounce back and want to fall in love again and want to be open and vulnerable. 

But things are different now...

But it isn't that simple anymore. The last two guys I've dated and fell hard for lied to me and I think the most recent guy has a fiancé (neither I nor her knew about each other obviously). But I don't know and that's the problem. I have doubts about what he tells me but I can't confirm.

I guess what I'm getting at, is love really worth it? Is trying to find love really worth it? I've been so sad these past weeks and I've been trying to repress the memories of the last few months. I thought it was going well but I can't block it out anymore. 

I just want to cry. Why do people want to be in love? Why do people want to do vulnerable? Why do people want to give themselves away to the possibility of these feelings everyday?

I don't understand. Why is dating and relationships worth it? 

It just hurts so much. I keep trying to ignore it. I'll get better eventually, I know. But, for right now. I don't understand. I just don't want to fall in love anymore. 

I've conceded to a life of being alone and never vulnerable again.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I've become jaded to love, I don't want to be vulnerable and set myself up for this pain again. Is being in a relationship and being in love and being vulnerable really worth the potential pain?
