What to think?

My boyfriend took an old friend for a drive to the hills before I moved from my home state to his. This friend is a girl who is dating someone else and has two kids from other guys (not including the one she’s with). He didn’t tell me he was going for a drive with her until the next day when I already figured it out anyway. They went out at 8 pm and she left her daughter with her cousin. They didn’t get back until 2 in the morning because my boyfriends truck got stuck and a guy friend had to give both of them a ride back to town.

I’m pretty sure nothing happened since he actually told me what happened before I even asked him. I also got an Oregon number and texted the girl as one of her guy friends asking if anything happened and she said no. He also drove from Oregon to Montana and back to help me bring my stuff here. A lot of people have said if he would have done anything, he wouldn’t have wasted his time or money to do so.

I guess my mind still keeps going back to that situation. Another girl I know says that she isn’t a good person at all and loves to hang off of guys as well as accuse them of doing stuff to her (including forcing her to have a kid with them). She won’t reply to my messages on Facebook (all of which are nice) or accept my friend request. I know it doesn’t mean much, but the fact that she avoids any communication with me whatsoever is suspicious to me.

Can I get other people’s thoughts? I’m just stuck.

Additional info: She has cheated on people before. My boyfriend knows what I did. They were hanging out by themselves with nobody else around. They have history together
