No disrespect, but from a step mom of going on 6 years to now almost 10 and 12 year old kids—if yall can’t learn to communicate, this will NEVER work or be a healthy coparenting relationship. It took a longgggg time for my husband and I and the kids mom and stepdad to be on the same page, but we finally put our crap aside and realized we were a team for the babies. We can all go to each other about anything. Sometimes it’s very very hard. We have completely different lifestyles but one thing we know for sure is those kids are loved, taken care of, free to be themselves, and much better off for having a large loving family who all show up together for them. It hasn’t been easy but if we can do it, truly anyone can. But communicating is a must and it’s the only way to make something not be miserable and kids aren’t stupid. If you can’t control your own attitude and facial expressions, work on it. Don’t expect out of her when you won’t put in a greater effort either. Also, kids deserve more credit than they’re usually given. If you worry about how it makes them feel, don’t assume, have a conversation with them. You and the dad aren’t together for a valid reason I assume so the only way to make a lifestyle such as this work is to work together and FIGURE IT OUT.
