Welcome to PC! Glad you could post about all that is going on.

I'm guessing you realize that the communication between the ex and your boyfriend will be something that continues considering they have a child together. I'm not sure how long its been since there were "on", but it will take some time for your boyfriend to get some boundaries in place. Hopefully, he sees what the ex is doing...being manipulative and controlling as you posted...if not this may be the best he is capable of... which leaves you in a position of accepting the intrusions...

Getting feedback about being bored and unhappy...is that your conclusions based on something else he said or did he use these words when he described how he was feeling. If he used these words, I'm guessing these would be a big red flag to tell you that this relationship won't make it much longer whether or not the ex is involved. If these are words you used to summarize how you felt about a conversation, then it would be worth getting further clarification from him.
