I'm in a long distance relationship and I recently found out that the guy I'm seeing has a really close friend who is female. I'm already finding the distance thing really difficult because we only started seeing eachother about 3 months ago while he lived near me but 3 weeks ago he moved back home to where he is originally from and it's a 6 hour drive from me. It turns out that he has been in contact with his friend and they have been out together and I feel this awful jealousy which is something I've never felt before. He said they've been close friends for years and that nothing has ever happened between them, apparently she likes him and her family think he would be good for her but he said they are such good friends that it would be like kissing his sister. He also just found out she does drugs which he really doesn't like in a girl.
I trust him 100% but my paranoid/jealous side is coming out and I'm really worried that he will develop feelings for her now he is living back near her permanently. I can't stand the thought of him picking her up and taking her out and them laughing etc together. I feel like this is my issue though, he can chose his mates and who am I to get between a close friendship when they've known eachother for years and we've only just met.
I don't know whether to be honest with him about how I'm feeling or just keep quiet. I started telling him how I was concerned he was going to meet someone else and he said he doesn't like paranoid women, he told me he's not looking for anyone else and he often talks about seeing me again, so I don't want to drive him away. At the same time this jealous feeling I have is eating away at me and I can't really cope with it. What should I do
