I (20f) was recently diagnosed with BPD and when I read into it, it does make sense that I have it. I’m in a relationship with my bf (25m) and we’ve been together 2 years. Recently (maybe within the past year or less) we’ve been fighting more and I feel like he’s lost his patience for me. He says he loves me and wants to be with me, but I think I’m toxic to him and that’s why things haven’t been very good. He’s always short with me and doesn’t want to be around me. He will tell me he can’t tell me how he feels because of how I react and I try to be aware of this but sometimes I can’t help it. For example: today I was driving with to go pick up a prescription for him after a day of errands. He told me I could pick wether to go home or pharmacy. I told him to choose because I didn’t care either way. He insisted I choose. I hate being in charge and this made me anxious so I told I didn’t want to choose and he said that was annoying. This made me upset so I told him that it was messed up to say I was annoying. He’s STILL mad 45 minutes later, avoiding me and I feel awful and so alone. I just wanna die basically.... this seems small but it’s things like this that make me question everything about how I react and how I feel.  I feel like I’m constantly down and it’s because of this relationship. I think he feels the same. 
Do you think we’re better off our separate ways? I personally feel I’m bette off alone since I seem to ruin people. 
Any advice or any relating stories, feeling, ect are welcome.

I also started lamictal three days ago I’m only at 25 mg nightly.
