Hi Flower,
Your boyfriend is aware that he has a lot of control over your emotions.
When you get jealous and he consequently stops talking to you for days, he is exercising this control.
He knows that he can talk to all these girls that he meets on social media and meet them for coffee without having to worry about the consequences.
He doesn’t value his relationship with you.
That is why it is so easy for him to break up with you for no good reason.
He demonstrated this when he split up with you because you didn’t help him kill a mosquito.
He may be treating you this badly because he doesn’t believe that you measure up to his ex.
He just started talking to her after a ten year split and they talk almost every day.
The more he talks to her, the more convinced he may become in believing that you are just not as good as his ex.
This kind of sentiment may be the reason why he chooses to continue disrespecting you by talking to this ex as well as other female “friends” that he adds on social media.
He just doesn’t believe that you are good enough for him.
As long as he feels this way, he will continue being insensitive towards you.
