Welcome to our forum.
Sounds like you are starting to "negotiate a peace" with your primary/monogamous partner. We all make mistakes and we have to learn from them; it seems to me like you guys are doing a good job of moving forward, and looking toward a brighter future for both of you.
If there's anything we can do to help out, let us know. Read lots on this site, do searches and tag searches, and post when you have any thoughts, comments, or questions. This is a good place to get support and perspective from people who've been where you're at.
Just take things in little steps, and you will be fine, I believe it.
Love means never having to say, "Put down that meat cleaver!"
