I Need Help Please!

Sorry this might be long but plz I need help... So my boyfriend is up at college 3 hours away and he's a golfer. So if people don't know what it's like to date a golfer well it can be very stressful. So I saw my bf last weekend for 2 days and before that I hadn't seen him for 3 weeks now and now I'm going 4 weeks with out him... I've had a terrible past with a boyfriend that would go weeks with out seeing me and I formed trust issues anxiety and depression.. Now I'm getting controlling with my boyfriend and I and him both love each other very much.. And all I want him to do is sit in his room bc I get jealous of him hanging with the guys and some girls sometimes... I don't know what I should do bc every night we fight bc I get sad and depressed and he doesn't know how to help me. Sorry it's so long but I need advise!!! Plz!!
