Replying to Relationship problem

hey my name is kelly and I'm using my friends account to ask my question Been with my boyfriend for 4 months now. We are really happy together, i love his family but he hasn't met mine yet. We live an hour and a half apart and only get to see each other twice a week. Right now I'm focused on finishing school, looking after my little brother, spending time with my family and preparing for a trip. I know it's going to be harder for us to see each other and i feel like a bad girlfriend for not dedicating time for him. I feel like i'm holding him down. He says he's ok with this and wants to try and make it through this time but I feel bad. I told him i think we should break up and maybe try again in two months when i'm home and the timing is better. I just feel like he's waiting for me. Should I stick with what I think is best for him(breaking up) or should we keep trying? Should we just take a break and try again when the timing is better?
