<human>: My boyfriend and I have been together for two years, but in the last 3 months, we are on-again, off-again. Lately I feel like I've outgrowing our relationship and I'm starting to resent him/becoming bored. I am 24. He is also 24 and finishing his bachelor's degree, but he acts 20. He goes out to these terrible college bars with his friends who are 26 and act 18, playing beer pong and binge drinking every weekend. He has not had a job or an internship in the past two years because his parents pay for everything (and I usually am the one to foot the bill if we do go out). I have tried to go out with him and his friends and make an effort, but honestly its just not me. He puts his family and friends first and a lot of the time that means canceling plans with me. I have also been suffering from depression and have had a lot of family issues in the last year. I am thankful he has never had to go through what I have to go through, but he just doesn't get it. 

The thing is, he's not a terrible guy, he's just immature. When it's great, it is really good and I truly love him, but I'm just not in love with him anymore. The last straw is that his Mom controls everything because she's his paycheck (she pays his bills and college tuition). She tells him she thinks I'm negative and it's time to move on. He listens to her and she makes me feel terrible about myself despite the fact I have sacrificed a lot and continue to put him first and neglect my own feelings. I am going away for 3 months in May for an internship. Deep down it also bothers me that he is not ambitious. 

Should I break it off now or should I wait until before I leave? Should I suggest a break? I am not sure how to handle this because I don't want things to end on a sour note. Like I said, he is still my best friend, I'm just falling out of love. I just want some time to focus on myself, regain my strength and heal for once.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm (24) and he is (24), I love my boyfriend, but I feel like I have outgrown our relationship. I am going to be away for 3 months on an internship. Should I suggest a break?
