Married Life
Sometimes, getting a text message from an old friend can be really lovely, and sometimes it can be so out of place that you need to just shut it down. Exes, for example, do not fall under the category of old friends that you want to catch up with every once in a while. In fact, it is quite the opposite interaction, actually.
I think the real question is, why does this guy still have his ex’s number saved in his phone? I mean if he still has her number, then he definitely still has her social media and surely knew that she got married. The way his ex cut this back and forth short, further points out how happy she is without him. That must cut deep, but who cares, he needs to take a hint.
