I don't know what to do

I had my period for nearly a month, in that month I gave my boyfriend like 3-4 blow jobs and I told him tonight I'm off my period and he's like 'yeah that's nice' then went on his phone..

he never seems interested in having sex with me, and when I bring it up he always says 'is that all you ever think about'

It actually broke my heart that he yelled at me and told me it's all I think about after asking to have sex once after bleeding for a month..

I have a feeling he's sleeping with someone else or something.. idk, I'm just really self conscious right now 😭
