The DH here is not man enough to express pride and joy in his own newborn baby and has thrown his wife under the bus several times trying to impress a friend who is a complete loser.
Are you psychic? I went back and read all of OP's posts. She never posted that her husband threw his wife under the bus "several times trying to impress" this friend. He just said OP should ignore friend's rude comments. OP also posted her husband hasn't seen this friend much in the past two years, and was easing friend out of his life.
I think the advice to go through husband's phone is horrible. It indicates a complete lack of trust. They may as well just call it quits now.
OP, either you trust your husband or you don't. Contrary to what you read into his text (assuming your first post is accurate), it doesn't sound as if your husband said you are tedious. With COVID-19 lockdown, being stuck in the house, even with a newborn, can be tedious. In normal circumstances, you would be going out, showing off baby, or having relatives in to see your baby. You'd have routines in place. You would be out shopping, taking long strolls not only outside, but in shops. Your husband also likely would have been working before your baby was born.
Right now, if you were anything like we were, you are sleep deprived. You are extremely busy. And you likely don't have the supports around you that otherwise would have existed had there been no COVID-19 crisis. So, take a deep breath, calm down, DON'T look at your husband's phone, and try to resolve this. Don't make any rash decisions until the COVID-19 crisis has passed, and your hormones are in better balance (for me, that took four and a half years, but I had three pregnancies in those four years).
