So I've been in a sort of relationship with this guy for a few months now, but we are both really busy so it's been a month since I've seen him in person. I struggle with anxiety so it's been really difficult for me because I miss him a lot and it's easy for thoughts of him being with another girl to creep into my mind. He's always been really sweet with me and I worked up the courage to tell him about my feelings a little over a week ago and he was very understanding. We also established that we're exclusive which made me feel a lot more secure, however, lately he's been distant. He's been going days without texting me unless I text first, and I set up two times in the last week we could hang out that he's made excuses for not being able to come to. He apologizes profusely and of course I tell him that it's okay and support him, but I actually feel really shitty about it. I don't want him to put me before everything else, but he hasn't really made the effort to see or talk to me over the last month and I'm confused because why would he want to be exclusive if he doesn't like me?! I've been getting input from my close friends who know the whole story and they said I should end it but I'm not even sure how I would do that. I still like him a lot, but my first instinct is to run away so I don't get hurt anymore. I feel like I would come off as needy if I talked to him... What should I do?
