So my ex posted a pic yesterday on social media of his child going back to school (he was not in the pic). I typically do not like his pics, but as I was scrolling I saw it and liked it, I didn’t think anything of it. My sister is friends with him on social media as well, saw that I liked the pic and called me this morning saying she couldn’t believe I liked it, and now he’s gonna think I want him back (she’s a bit over dramatic lol). I really didn’t think it was a big deal, it’s not like he was in it. Plus he’s liked quite a few of my pics. Is it really that big of a deal that I liked a pic of his child on social media?
