Need advice!!! (i’m desperate😭)

First i have to tell a little of backstory, so me and this guy kinda hooked up 2 years ago and i felt really strong feelings for him because he treated me good the time we were together. But after that half hookup he ghosted me and sent me only drunk messages, obviously i was devastated and felt used,not even a month later he got a girlfriend…

So now we return to today. After months and months, almost a year, i forgot about him and didn’t wanna know anything related to him UNTILLLL last week he wrote me again after 2 YEARS about getting in contact again.

4 the plot i answered in a mean way because in those years i grew some balls lol, after a bit of conversation i told my version of the story and how he made me feel and he said he’s sorry and he thought that i didn’t want a serious thing back then. (btw he and that girl stayed 1 year and 8 mothers together)

Now we are texting every day but i still have my guard on, but he really seems different because btw we grew and changed a lot since we last saw each other, and i consider to kinda give him a second chance and hang out with him and see how it goes

I would really appreciate some advice and let me know what would you do if you were in my situation <3
