Affiliate Marketing Secrets

I’m 18 years old. i have been “seeing” a guy for about 1 month now. He is also 18 (about to be 19 soon). My friends have told me that he is a bad influence and disrespectful. They have told me his is gang affiliated. At age 18 he already has three mugshots and has been expelled twice from school (only lasted 2 months at his last one). I want to like him but for obvious reasons in apprehensive. I think he is funny and a great guy but his past scares me.
What do you think?
Is three mugshots and 2 expulsions a lot to rack up for 19 year old?
I need some genuine advice. 10 points

Well , my friend recently told me that her period was late & she said that someone is going to sneak her a pregnancy test after school . At that time I wanted to be there for her because it’s a hard thing to deal with . After the test came out negative , it was a relief ! But it’s been a week & we haven’t talked. I honestly don’t want to talk to her because she is sexually active (Her & I are only 13) I just feel like she is a bad influence. She told me she has had sex with that guy multiple times. At my school I don’t affiliate with the sexually active girls mostly because they aren’t my friends, but should I make an exception for her ? & if not how can I tell her I don’t want to talk to her because of this incident without being rude ? I think 13 is WAY to young to be thinking/having sex. I want to tell her this without her feeling completely disrespect because she is VERY emotional !
