So I've been trying to communicate with my boyfriend since months trying to explain how I feel in this relationship.

This was our chat today

ME: I lie to my parents I fight with them everyday for u only to come to ur house so u can be on ur TV or phone and I sit or lay there until we have sex- that's all. What am I too u please tell me time pass? This, I deserve a little more then ur damn divided attention. That's the least I deserve.
You've left me traumatized since the trip for something u did u broke up with me and I still came back cux my love is real for u. I'm still hurting and u don't care. And then u talk about abortion and foster care and ur defense is it was a joke. This relationship is nothing but unanswered questions for me im so confused since the trip. I'm so lost and unhappy since the trip I can't do it anymore and u idek man idek how to word it!

HIM: So I've changed
I guess yea
My attention is less yes
Do u wonder why

ME: why?
HIM: You can't tell?
ME: Tell me
HIM: I've said it so many times. But you just I don't know man 70% is you. Rest is just time.
ME: Explain I dont get it u have to explain it
HIM: later, imma sleep
ME: no before you leave just know.
I am done with you don't message me im clearly understanding what your doing. I don't need you and ur left over time for me. Stop fucking around with me by giving me ur left over time. Just get out of my life and leave me please. I'm not some trash u can shove up ur priorities up ur ass I'm done dying for u 70% me and the rest is time? Where is this fucking time when u spend it with others else where when u spend it on TV on ur phone- no fucking efforts and here I'm being stupid ready to lose everything for you. Done with you. Ur free to go.

I EXPLODED GUYS AND I FEEL LIKE ILL REGRET IT BUT I can't BOTTLE IT UP ANYMORE I JUST NEED SENSE OF THIS CHAT. ITS DIRECTLY FROM MESSAGES.
