All women are strong, if we weren't human beings would cease. You just need to find your inner warrior. I was miserable in an abusive relationship and my saviour was joining a gym. I had 90 minutes 4-5 times a week where he wouldn't interfere and my mind was free. I used strength training to get strong mentally and when I felt the time was right I left. I'm not feeling particularly strong at the moment as my health isn't great and I didn't feel particluarly strong at the time but I knew for my mental health I needed to get out.
Things I did:
Wrote a list of the things that made me feel good about our relationship and the things that didn't. The negative list was three times as long as the good points.
Had a big kick up the ass in terms of diet and health. I don't think I could have done it if physically I didn't feel strong.
I spoke to some trusted friends and family, really opened up. I always kept things from people as I am quite private. Once I started sharing and people told me they could see I wasnt happy, it felt more real.
Worked out if and how I could manage financially. I started withdrawing a bit of cash from our joint account and saved it (we only had one joint account and all my salary went into that, he wasn't working at the time).
I worked through all the guilt about "splitting up a family" in balance between having two miserable parents (kids are much happier).
I Posted on here quite a bit, and was overwhelming the support I received.
Then one day everything clicked into place, I knew I was 100% done. I told him, moved into a rented place with the kids and he stayed in the family home. Last two years haven't been easy but I am a whole lot happier and free again.
You say toxic, is it abusive? How is your housing situation?
