I read your original post and felt like you both made honest mistakes and weren't trying to hurt anyone. I'm very glad to read that you both have admitted and realized the same thing about your own and each other's mistakes, and are going to try to work it out. Just remember: it's OK if it doesn't work out. I hope it does, and I can easily see how it would since now you both will be working actively at building trust and communication with each other, intentionally, to specifically avoid another such situation (plus, therapy). I just want to point out: "It is possible to commit no mistakes and still lose. That is not weakness, that is life.”― Jean-Luc Picard. The important thing is that you're not giving up now, at the start, when not quitting matters very much, maybe the most, because this is when your investment is lowest, and the losses to cut smallest. Keep working, and if you believe in the future of the relationship, choose the relationship and the future as much as you can without compromising your integrity or safety.
