Not LO related, LIP-related post

need ur thoughts mga mamsh. Live in kami ni partner since 2019. May ex si hubby for 8 yrs back in the province na syempre super familiar na sa buong angkan nya. Namatay yung parent ni hubby and as expected, nandun sa girl to pay respect. They r friends hanggang ngayon, may gc sila and all as in active friends. I dont mind kasi married na si girl with 1 child. Maraming eksena si girl dun sa wake ng parent ni LIP and still, i dont mind. She's super close with everyone in the family and i don't mind kasi naman 8 years diba? Di ako jealous type and I can confidently say na i have an open mind to almost everything. They even had numerous close body contacts coz of random things, and still, i never felt anything. This girl has a warm personality kaya everyone in the family is very welcoming talaga sa kanya. She's nice to me too. So okay lahat, nalibing si in-law and the following day we'll be going back home (we dont stay in the province). It was then that he accidentally called me his ex's name in front of his siblings and some relatives. And he was like deadma. Not even sorry. Okay, so a friend told me na it's no biggie kasi it happens talaga. On my part, it's the first time and I was(and still) thinking na he got distracted dahil sa ilang beses silang nag meet ng ex nya this time. it's been days and I'm giving him (not so) silent treatment. Kahit anong convince ko sa sarili ko, i still feel bad about the incident. OA bako?
