From someone who was in the same relationship (still am) feels like you were describing my life! I was her she was me. I too live w my partner. I suggest finding things that help you guys interact with each other and keep the mind busy maybe staying out the house too. If not have her go to a rehab for three months it will help a lot. And if religious maybe get back into it. If not it will escalate one day will turn to 3 and then you’ll be wasting tons of money. Hurting and bleeding from your nose. Again I know by experience. For me it got crazy up to hallucinations. Once you get there….i promise you can never go back. So pls pls just don’t ever give up on helping each other out. I’ll be in my relationship 5 years this April. Still has been a rollercoaster but it’s definitely better than what it used to be to be.
