So me and my partner have been together for 4 years . Both of us have done things to ruin each others trust but decided to work through it all . But I find myself still not being able to trust him … My walls are up completely & I don’t know how to let them down . It affects our everyday life and it intervenes in our sex life as well . Anyone have any advice on what I could possibly do to become vulnerable with him again and let down my walls ? I don’t want us to continuously keep going downhill as we are now . Things have been rocky for about 3 1/2 years
