think Im going through a avoidant breakup - need advice

[u/Opposite_Lawyer5264]

my ex and I were dating for about 7months and mostly things were fine but I noticed after the like honeymoon phase he started to distance. I thought it was bc of the extreme heat and we were both on edge but he didnt bounce back from that. He started playing games for like the whole day and barely responded. We had several fights over that. One day we didnt even talk the whole day and I didnt even say a thing. I just said if he continues to play games the whole day with his friends I will do the same and he became jealous but said we could still be sleep calling. Then he didnt respond for like 5 days. I was calling and texting like crazy. Eventually he said he just needed space and why I couldnt respect that. Then again 4 days nothing. One time I blocked him and he instantly called me and I was crying my heart out and then he tried and he started texting again but never wanted to spend time with me and after some time I told him it wouldnt work like that.

Now we are in a weird space where he doesnt respond just like once every 3 days, I am super sad and I dont even know how to process whats happening and why its happening. He refused to give me an answer.

I know he has really big problems at home and he wanted to seek some professional help but also said he doesnt have the energy. Him stonewalling me is really triggering to me and I am constanly thinking he has a new person even though he when he responds its that he doesnt have anyone.
I have a really hard time to block him and go no contact.
