MY EX IS WEIRD PLS HELP

So i have ex(lets call him Alex) so we dated back in 2024 for 6 months and seperated our ways, no anger or anything just going to our own paths, then on January 8th this year he texted me that im only woman he truly loves and said hes drunk. He deleted messages and i pretended as if i didnt see them, but i did. Then two days ago i texted my old friend thats also friend with Alex and Alex asked for my insta so our friend gave it to him. Alex texted me and said how i am and stuff(short convo) and he added song lady by modjo on insta notes and its song abt guy liking girl. He didnt text me today, but what do yall thing??? My boy bsf said Alex still likes me, but idk what to do besides ignore him and stay dry texter towards him (Alex is on school trip now).
