Boyfriend Troubles PLEASE HELP

I have been dating my boyfriend for about 8 months now. We get along so great when we are together and we are so in sync. He is the love of my life. However, our relationship recently has gone under the stress of becoming long distance. Though we would have our little arguments here and there, we would usually be able to work them out the same day with a conversation. However, now that we are long distance (18 days apart at this point) I’m a little bit worried about some things. I feel like he is acting a little differently. He used to act so amazingly supportive and beautifully sweet and I knew that it was 100% genuine. Now, I feel like he’s retracting his support and treating me worse almost as if he is displacing all his anger onto me. He moved away for college and I know that this is an enormous stressor and I usually am very understanding. However, I also don’t like to let people walk all over me. I think the biggest things I noticed are he gets so upset if I don’t tell him immediately about the things going on in my life. I am a busy woman. I have a job and huge family and I also am attending college as well. On top of that, if I tell him about something in my life that may be a little bit negative (I won’t even complain about it it would be something like “ oh yeah I haven’t gotten my car fixed yet I’m still waiting for some help”) he flips out and asks why it hasn’t been done or gets made at people (who are doing nothing wrong) for not helping me fast enough. I’m caught in the middle. Tell him about my life and he reacts negatively. Don’t tell him about my life until problems are resolved and he reacts negatively. Another thing I am so very upset about, is the fact that I feel like he doesn’t support me or is judging me. I work very hard for things. For example, I want to help out a family member I will help them out 3 hours none stop because I think it’s fun! However, he acts like it’s so bad if I put in extra work. Another one would be for school. I do my work early and put in hours of studying for one class. I tell him about how excited I am and he freaks out asking me why I would study so long for that class even though it’s barely studied. Now I intend to get straight As in college and this is how you get them! I feel like he isn’t supporting me and it hurts!!!! I don’t understand. I want our relationship to get better. I know he recognizes that he’s doing things wrong and he’s trying to do better by him. He’s the type of person that works hard to get better if he knows what’s up. I’m just in pain right now. Also, we still have good moments too even though we are long distance, it just feels like there is a lot more negative than there was before. Any suggestions or insight would be greatly appreciated. I love him and I know he loves me. We are just going through a rough patch and want help.
