My boyfriend's female roomate loves my boyfriend…

Hello everyone,

I am in a relationship with a guy since 3 months. Everything is going well and he already told me he loves me. He comes from Greece and came here for his job for a period of 9 months. He will go back to Greece soon but we will do a long distance (2 hour flight so its fine).

When he arrived, he found a flat with a girl he knows since 10 years. She is 10 year older than him (40 years old but superficial, very blond, low neckline etc…). We are both 30. When he started dating me, she also started dating a “local” guy.

One day, I was watching a movie with my boyfriend and she arrived dressed with only a bra. I was really shocked. My boyfriend said that it make 4 months that he lives with her and he is used to see her like that and her as well saw him wearing a pant. He told me he is not attracted to her because she is old and he doesn’t like her character.

Few days later, I felt that I was disturbing them when I slept in their places while she was there. He was often telling me that “I should go back home because she doesn’t want us to make noise at night”.
One day, I slept in their places while she was there (usually i sleep there only when she goes to see her boyfriend) and she gave me a dirty look and didn’t talk to me at all, not even a “Hello”!
Every morning, she usually goes to work with my boyfriend with his car because they have the same job. But this morning when I slept there, she said goodbye and left the house slamming the door. He was surprised and told me “that’s weird, i don’t know what she has but i don’t care”.

I think that this girl is probably in love with my boyfriend. This situation makes me feel very unconfortable because they both live together. They finish work at 4 pm and i finish at 10 pm and go back home alone.. They have plenty of time to do many things together. Unfortunately, I live with my parents so I can’t offer him to come…

This situation makes me feel crazy. I already explained to my boyfriend but each time he just doesn’t undersand me and hates seeing me jealous. He said that if he wanted to have sex with her he would have done it before and won’t have bothered going in a relationship with me.

I would like to have some advise because I feel so bad.. Each time, i mention the subject he sais that he doesn’t have the choice and lives with her and that she is a friend. Sometimes, I feel so bad that I just want to break up with him because I can’t focus on my work because of that. What do you think and what can I do?
