i so badly want to try again with my ex

my ex (18m) and i (19f) broke up about 4 months ago, but we still had each other on our social medias. after we broke up, about a week later, he got into a talking stage with someone that lasted about 2-3 months and they stopped talking.

he knows i want to try again, but neither of us are ready for a relationship at the moment. i can tell that he somehow still likes me? as well as his mom (his mom and i are very close) he thinks that he is genuinely still interested in me.

he shares posts on his social media about him having a crush on someone as well as his my-day’s (in which he told me before that his ex talking stage constantly stalks him, and how his posts are now public when it used to be viewed by friends only.)

we haven’t talked for about a week now, in which 2 weeks ago we were talking daily after (just playing games and talking until we slept) and i honestly miss him. he never missed a single instagram story that i posted, and he even sometimes reacts to my stories.

i miss him. so much. his mom told me that they (my ex, his mom, and probably some relatives) would visit me here in my city (we were LDR) and that she still thinks that it’s likely that him and i will rekindle our love. i want to try again, and call me selfish, but it hurts me so much to see him posting these posts about liking someone else (or idk maybe it’s his way of making me jealous or the ex talking stage girl).

what we shared was special, and even after many months later, he’s still my comfort. i don’t know what to do. i don’t want to seem like a creep to message him every once in a while. i don’t know what to feel. 🙁
