Controling boyfriend

Okay last night I asked him to check my cervix cause my fingers are really short and I can't feel it

I was trying to see if I was ovulating

Or not

So he did it he pulled his fingers out an started to freak out

Saying what is this white stuff I told

Him its discharge he washed his hands off an came back an started to quiz me like I've cheated or let a another man nut in me

Question why would I let another man nut in me if we TTC

An on top of that how can I cheat if I'm always in the house?????

An I'm not allowed to go anywhere but to the mail box an back???
