I feel like my boyfriend is acting suspicious so I'm going to beat him.
I hope you are just joking. Why would you want to beat your boyfriend?
I want to test his reaction and I want to see if he returns my feelings
It is wrong to beat your partner, the police can be called and you will be arrested. It is better to seek some couples counseling.
I won't stop. I'm trying to make him feel how much I love him.
That is not showing him love if you are beating him. You should not beat your partner no matter how upset he makes you. You should talk to him more and communicate your feelings to him.
