Has anyone here kept around someone who cheated on them early in a relationship and not regretted it?

boyfriend (ex?) just told me last night he cheated on me two weeks ago with a coworker and hes so sorry and all that. I've not experienced this before and my immediate instinct is to stop being foolish, and break up with him immediately. my more sentimental instinct wants to give him another chance. you know its so easy to tell your best friend that she deserves better and should leave the asshole, but its so hard to follow through yourself.

somewhere inside im pretty sure that i would regret the decision to stay together, but i just havent had enough of him yet. it's only been three months, and we've done that stupid thing where we spend every waking moment together since the first day we met. ironically, the one saturday night we are apart, he fucks a coworker.

any seasoned advice would be much appreciated.

btw, i'm 23 and he's 27 and this is only his second serious relationship and my third, if that gives you any insight.

I wouldn't be able to stay with him honestly. The trust would be completely gone. Will you be happy being with him knowing that he cheated? I know that I'd be miserable.

I really cant tell. i dont know if i feel so horribly just because he cheated on me or also because i can't see keeping my integrity if we stay together, which would mean i have to break up with him. it's like he left me no choice. i dont know if this is something i can get over and stay with him, i've been physically ill and sleepless for the past 24 hours.

I think it would be best to call it off. It's only been three months, you're still in the "honeymoon" stage, and he's already cheated? It strikes me as bad news, although it was decent of him to tell you instead of finding out through someone else.

i would dump him especially being that it was w/ a coworker
thats way too humiliating
my ex did the same thing except she wouldn't admit to it
i dumped her because of it
always best to follow your immediate instinct
