Ex reached out

Ex reached out on dating after we split a year ago. Wasn’t a bad breakup, more of just sudden and random due to him deploying soon and not being in a good spot emotionally. Defs had to do on his end, not mine. Anyways is this him just apologizing or is this him kinda trying to slide in? With him mentioning he’s changed since. Tbh I really do miss him, and never fully got over him and think of him a bit.
