<human>: My boyfriend's father owns a dj business, and so a few weekends out of every month, he spends one night at a wedding assisting his father. This is sorta a bummer sometimes because it is usually a Saturday night and we can't see each other.

Last week, we both ended up having to work Saturday night and we were texting each other throughout the night until my phone died.

Next day, my boyfriend says he wants to make it clear he has nothing to hide from me and he danced with a girl [20 yr old] that was from several states away who approached him and he felt bad so he danced with her, but let her know he has a girlfriend and she offered to be a practice dummy for him so that the next time we danced together he could impress me by dipping and twirling me.

This all made me slightly uncomfortable, but I appreciated his honesty and chalked it up to PMS that I was a little jealous (totally not a normal emotion for me, am usually pretty lax when it comes to other girls).

Then he said he had one more thing to tell me, but he didn't want me to freak out. She had given him her phone number because she "felt comfortable talking to him and needed someone to talk to sometimes". This made me VERY uncomfortable and I told him so. He admitted that he had talked to her already and I made it clear I was not happy with this situation.

Like I said before, I was blaming some of my reaction on PMS because I get very, very emotional before starting my period. I am allowed on his phone and noticed that he has communicated with her one time since in brief conversation (it was his birthday), but I can't seem to shake this feeling that she is a snake in the grass.

I trust my boyfriend, but I'm struggling internally with the intentions of this girl.

Can you condense the text into three sentences or less?
<bot>: Boyfriend met new girl from far away he would like to be friends with, but I can't seem to shake jealous feeling.
