Nc for this and not enabling voting as already think I am probably the unreasonable one here.
For context, dh and I have been married 5 years and together 12, we have 2 dc, the youngest is 3months.
Last night dh received a text at 11pm (why so late?) from an old girlfriend, his first love that he dated over 30 years ago now. It was a short message, just asking how he was and had 2 kisses at the end. He showed me first thing this morning as, coincidentally, he had mentioned her the other day and he was surprised to hear from her. I asked him if he was going to reply. I wish I hadn't. Jealousy is my worst trait. It doesn't show often but when it does I dont think as rationally as I should. He said he was as it was like catching up with an old friend, that she checks in every 10 years or so.
I dont think he should message her back. I wouldn't message any of my ex partners our of respect for DH. I dont think anything untoward is happening but we are so tired with the new baby and toddler and I dont have much energy past a quick hug and a chat right now. I don't want him to think the grass is greener.
Also, it's been years, what could they have in common now? It's not like catching up with a mate at the pub, it's talking to someone you were once intimate with. I know I'm showing my ugly flaws here, I'm overthinking and showing some insecurities but would you be ok with it?
