<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've been cheated on a few times before. My first GF in high school cheated on me after a year. I had to break off a three year relationship with a girl when I was 22, after I found her FB messages. Overall I think there was one time where a relationship of mine ended that was not due to infidelity.

When I'm in an exclusive relationship I keep it that way, maybe people pick up this and play me for a fool. Maybe I am, I don't know. After the last relationship ended 3 years ago I've was trolling around bars looking for one-night stands to meet my needs. Its wasn't really satisfying, and successes were few and far between so I ended up meeting this girl and hitting it off, and we've been together since.

I started noticing the signs earlier than I'd admit, originally I thought I was paranoid because its happened before, but you can only ignore so many unexplained nights out, or the sudden influx of all these old friends I've never heard of.

Compounding this I've recently heard some pretty depressing shit from some other girls. An old friend of my sister got drunk with us not long ago and was literally bragging about how often she can go out and cheat on her boyfriend and get away with it. Another woman at an office party told me about how groups of her married friend will go out drinking and **take off their wedding rings** halfway through the night.

Is this a common theme nowadays? Has it always been like this? Should I just expect my relationships to end this way? Does it stop when people get older? Maybe its not helping that I'm reading shit like [Why cheating is good] (saying women SHOULD be cheating) and [this shit] saying 40-70% of people are cheaters.

I just feel like a mess right now and I feel depressed that my best option seems to be banging drunk chicks every few weeks and never talking to them again.
<bot>: Feeling like I should just expect to get cheated on at this point. Am I losing my mind or is this really the case?
