Long story short. Me and my partner have had a rough time due to one of his other relationships not working out and it has spilled over into our relationship, mainly through him being sad/devastated or deprioritized our stable relationship to save the chaotic one. It hasn't been pretty, but there is not a lot he can do about it now. The chaotic relationship is over since about two months, but their struggle to maintain a friendship still affects us.

My issue is that his emotional roller coaster became my emotional roller coaster and I have developed a lot of strange triggers that I'm not used to having. It can for example be to worry about what he's up to when he's not responding to texts, I get anxious straight away when I hear her name and I feel exausted straight away when he needs/wants to talk about his other relationship.

I'm usually not easily triggered, jelousy is not a big thing in my life and my emotions are usually quite well balanced. But right now I can feel my emotions reacting too fast and too hard to even small triggers. I feel like this is damaging our relationship, and that its unnecessary. The roller coaster should be over now, but it's lite the fear lingers in my body.

How do I get rid of the fear in my body? How do I get back to my stable self again? Is "give it time" the unit thing I can do?
