I’ve never used Reddit before and honestly it still confuses me. But i don’t know what to do anymore. my girlfriend and i of three years have been fighting constantly it seems like for the past 2 years and i always feel like it’s all my fault. she tries to understand and i love her for that, but it’s just not enough sometimes. i lose control of myself and my anger and i feel like a complete failure. i don’t know if it’s the fact that it’s both of our first relationships or if it’s my BPD or a combination of all three. i can see her getting worse and worse in this relationship and i know it would be best if we broke up for good but she’s all i have. without her i have absolutely nothing. and she has nothing else either. i don’t know what to do but i can’t keep doing this..... any advice is appreciated
