Hi guys, gals

i have been seeing this guy for about 6 months now. Everything went well up until a month ago. We didnt see each other much since I work and go to school at the same time and my schedule is very tight, but when we did see each other it was always nice and warm. We talk and text message all the time. He is really sweet at least he used to be. About a month ago he started to get really rude and disrespectful towards me. It hurts me when he is like this. Also, it's like he has mood swings or something like that. I never know how hes going to react to my phone calls or messages. I hate thinking that I did something to piss him off. I try to be extra nice to him when he is having one of his bad days even if it makes me feel sad. I am not the kind of person that puts other people down and he is. He puts me down and I put up with it cuz I care about him a great deal. He says he cares about me too, but deep down I know he is bsing. Just last week I told him that if I irritate him I want him to let me know. He said I dont, but yesterday he told me that I do, and that he needs time to think. He said he cant take too much of anyone. I mean we have seen each other maybe once a week throughout this whole time and he tells me he needs time to think. Making me look like im pushing for something. I dont know, im very confused and I am starting to feel remorse for him. We were really good firneds before any of this happened. I feel hurt and sad because I tried so hard to satisfy him and then he comes up with this. I am starting to think I gave to freely. What should I do? How should I approach this issue? Please help!!!!!!!!!!!
