<human>: Provide a brief overview of the text.

My girlfriend has had conversations on a very regular basis with a friend of hers, let's say "Bob" who she recently told me that she had feelings for 2 years ago but was rejected by Bob. Claims she hasn't had feelings for him in a year and a half. I don't like Bob because he always drunk texts her and occasionally asks for tit pics. (She has NEVER sent any! ) I don't believe they have hung out for atleast the 3 months that I have been dating her.

This week I told her I loved her (she said it back) and am currently back at home on break. She sent me a text which was intended for Bob, nothing was bad in the text, just some conversation... but even just conversation bothers me and she knows it. She has made an effort for the past 2 months to not really talk to him as much in front of me.

I did not ask her to stop texting him, but definitely made it clear that it's something I wouldn't mind her doing because it bothers me that she used to have feelings for Bob and it seems in my opinion that Bob is keeping himself in her mind nowadays. She says she can't stop talking to Bob because he's a friend. They used to work together.

Should I make her stop talking to Bob? Am I extremely overreacting? What should I do to make myself feel better about her talking to Bob. I trust her completely, but don't trust Bob's motives.
<bot>: GF[22] had feelings for a guy, who 2 years later is texting her regularly when I[19] am her boyfriend. I'm bothered by it. What should I do?
