Do I move on or see what could happen?

Please can I ask for some advice as I can’t ask anyone else around me.. my ex has been asking me to meet him he lied about having a girlfriend but when I did say I have a boyfriend (I lied) he rang me begging to meet up.. he’s done it twice not and I have not seen him for over a year. He said he wants to meet up as friends. I’m not sure if I should? I don’t trust him and that’s what is holding me back how can you be with someone you don’t trust 100%.. i don’t know if I should meet him just to see him and see if I feel anything or if I should just leave it and move on with life. He’s usually so worried about what his family think so we did not go on dates together we just used to chill inside the house. I think because I was lonely there was some sort of emotional attachment there. I did tell him one time I feel like I’m just existing he didn’t really comfort me infact he just said two words if that. He’s obviously regretting it now as he now knows I was a good person. Should I let him regret doing me bad and move on with my life or get clarity from the situation and see what happens? And see if he actually wants to go on a date so I can see if he’s grown up abit and not bothered what his family think.. I just don’t know what to do 😫🥲 I have no guidance around me
