<human>: I'm not inexperienced in relationships 

My gf and I are both in the same class at college. We hit it off straight away, the start of this relationship was utterly perfect, I swear to you I met my soulmate and I just couldn't wait (literally) to ask her to be my gf which was about after 3 weeks of knowing her but baring in mind we'd see each other in class 3x a week 

**selfish part** Anyway things were all perfect but I think that was only because she used to be "lonely" like I was, now she's goten some new friends and I feel like she's just been slacking with me. Conversation isn't filling, she gets high without me, does everything basically without me. A part of me is really happy for her because obviously she's enjoying herself and what not, but another part of me really wishes that she'd lose her friends again so that we could go back to how we were..

**my conclusion** I think I'm too immature if this is becoming a problem, I mean i literally only use my phone for her and my mum and sometimes she'll randomly disappear during convo, leaving me to just throw my phone somewhere because I know she won't msg back for another 30 mins-4 hours ( no joke). And this makes me feel like I'm unimportant, heck I even feel resent towards her. So I just think that if this persists then maybe I should just break it off with her. Just need advice

Give me a shortened version of the text
