lust/love?

if your gonna judge- i dont wanna hear it, more looking for more curiosity/ opinion as im trying to work it out myself.
so my situation- I went through a pretty bad breakup last year, first long, long term relationship all that. I took my time to heal and became ' back on the market' in terms of being emotionally ready to date agin in summer. I had my fair share of situations - one night stands, dating friends, many dates, situationships ect ect. But theres this one guy. we meant on a nigtht out, and had mutual friends. Took him back to the house ( BLAH BLAH). we then see eachother a couple more times, but are messaging alot. Its been a while since I had any kind of emotional connection due to being so hurt, and i could tell this guy HADNT, In the big picture of things we must of seen achother a handful of times, but i cant get him out of my head. I talk to a fair share of guys ( again not in a sl4ggy way) but i dont get that emotionally invested. He broke the news to be that hes travelling over xmas, and that he cant even think about anything serious as it would be about 5 moths until he was home, to which i agree with. We had the convosation about being in contact but decided it was probs gonna be too complictaed - with things like different timezones, he sad he didnt wanna leave me waiting for messages and tbh, we hadnt established enough to 'wait for eachother'. i was ready to date and after a pretty traumatic breakup, i wanted to epxlore the world of dating. we send our final messages and thats that. My friends were like you will 100% hear from him, j let his excitement kind of go to travel and tbh i was expectingto, until one week, two week , three week passed and i didnt. I had temptations to message him, like at Christmas/ reply to insta stories/ new year but didnt. I then deletae all social media j because of exam week i didnt want any distractios, and when i log back on i get a HELLO message from him. when i tell you i jumped up i was so happy. it had been over 2 months since we spoke, im pretty quite on social media hadnt posted anything for him to be 'reminded' of me ect, so he must if scrolled quite a while to message me - but im just so happy - i wanna know what this means. Its weird i shouldnt be thinking about him so much as its not that deep, but i cant help thinking what this means idk.

How old are you?
