I don't know whether it is related to BP or not. You wanting to go with husband is obviously a good thing. Sometimes I want to pay a little more attention to where my wife is going when we have a argument or have a bad week. One of the things I have been trying to do is have my own things to do with friends etc... But how to you do this without having your spouse become even more distant from you? I usually ask her along with me or I just try to do my own thing when she is doing hers. I aske her if she had fun and what happened with her evening. Show I'm interested even when she is not with me. I find this goes back and forth. Somedays we want to spend every minute with eachother, sometimes it's like can you just leave me alone. I wonder how he would react if all the sudden you were out and about? Play it safe though. Let him know where you are if he asks. But it sounds like you might still be worried about what he is doing. I'm the same way so don't feel wierd about it. But you have to work that out yourself.
I think you love your husband very much. One of the mistakes I made with my wife is letting people think ill of her. I feel he should defend you if people call you arrogant. He's not thinking this way lately I'm sure. It's hard because I don't want you to lose respect for yourself and you need to show him that without starting a fight. Everybody is so different when it comes to this but try to come across that you are talking to him because you love him not because you want to fight or give him a hard time. You just want what is best for the relationship. Again it is hard to give advice because I don't if you are being sensative or have exhausted your efforts. But if you know you have done your best to make something work or to improve your marriage then take pride in that.
wish the best for you
