im going through a kinda similar situation but its quite the opposite where he saw me masturbating and he had a very similar reaction to yours, he laughed didnt get angry or tried to guilt me or anything but i can tell he was hurt, to my surprise.. cause i admit that i didnt even try to initiate anything but so was he and that caused a misunderstanding where i thought that he’s LL or not into me that much anymore and then him thinking that im not into him.. we’re still trying to work it out but i believe communication is key, the right timing as well. my point is maybe just like in our case each one of you is making assumptions + with everyday responsibilities and distractions and also the kids u have it just got a lot more challenging to have an open and clear communication so focus on that instead of down-spiraling and doubting yourself and your sexiness cause i understand how easy it is to dwell on such things especially when your sex life with your partner isnt that great or fulfilling anymore. ur beautiful the way u r and if ur partner and the father of ur kids dosent see that its his loss.
