Whenever i imagine my boyfriend being affectionate with his ex i feel anger. They're not together for a while now and they don't even speak anymore, it's been 8 months. She's far gone from his life now. 

However, whenever i think about him loving her before me and doing romantic things for her make me viscerally mad. I feel like vomiting and breaking everything in sight, as i actually did before.

I'm scared that he doesn't love as much as he loves her, or that he's just with me to forget about her. He knows about my worries and is very supportive, always reassuring me, even though he knows i struggle with BPD... he's literally the best and i love him so much, im just so freaked out about him not loving me as much and eventually leaving me, i dont know what to do 

I'm tired of being angry because of stupid shit like this
