Throaway because the person in question knows my reddit name.

I've been seeing a girl for around 5-6 months now. I've had 5 sexual partners since I turned 18 (I'm now 21.) The girl in question is 23 and has been in 4 relationships since she was 16. Now we recently decided to go exclusive, I figured 4 relationships is cool she seems sweet and level headed.

After starting a relationship with her just 2 weeks ago I was around her friends and they were talking about past sexual experiences, she seemed reserved about it and was almost trying to get them to not mention anything. From the information I've learned I've found out she had a fair share of one night stands between relationships, how many I don't know but I really don't think I want to know.

To add even more to this, just last week we were out for drinks. She drunkenly told me she loves me. I was shocked and said well I don't feel the same way. The next day she told me she didn't mean to say that and she's never said that to anybody in such a new relationship so early.

I feel like i've made a real mistake getting together with this girl with her shady sexual past and her confessing she loves me so early on it's a whole bunch of red flags. I would prefer a second opinion though as I may be looking too deeply into this.
