Chatting with you isn't hard for me as you've said, we're friends. Just that, no more no less. I know well of my attitude that made people feel hate on me but I treat people the way they treat me. If he/she treat me well, I'll have no doubt to treat them well and vice versa.
Seriously, I know Jennie and Mikey more than you do as I'm closer with them. What people belongs to what character, I'm well acknowledge too. In my world, I've seen clearly on what friends should I contact more and which one I shouldn't.
Maybe you're a bit right about my current boyfriend that he's a bit immature. However, not only he chose me but I chose him too. Despite no matter how immature he is,I must still accept and tolerate. Anyway, I should thank him for making me independence. Now I work on myself, didn't depend on him too much as I did it on you. So far, most of the time also I drove but sometimes he drove using my car so is alright to me. While about your personal lifestyle, I can have no say already as I'm in no post to do it anymore. If you're happy with who are you now then just go on. I also did the same way. I'm happy for who I am now. I can go shopping, do revision and part time job as I will.
I never regret an what have I done so far from knowing you, falling in love, being in relationship and finally broke up and being as friend again as I already let go what it should be. so just hope that we both can live happily on our own.
By the way, regarding your case, that depends on how much you weight your friendship and working. If you feel your friend is more important then stay with them but be prepare as you'll have to pay money to settle your degree certificate. If you choose working then as you mentioned earlier, if they angry at you just let them scold you a few bad words and treat them sushi king then it'll be fine else you also cannot do anything already.
