Should i call him or no and just forget him...?

Ok so last yr I met this guy at my bartending cles we started talkin and hanging out and then one day he just txted me and told me he had gotten back with his ex... so then a month ped and I called him and he told me he was having problems with his girlfriend and that she just wouldn't pay attention to him or anythng... so some days ped anf I thought he was going to break up with her but he didn't so then like 2 months ped I txted him and he was single supposely so we started hanging out again and .... but the thng is that between all those months he would disappear and reappear out of no where... he's 29yrs old he has a 5yr old daugther and he's "divorce"... I'm only 21yrs old and I was really starting to fall for him... but I just hated how he always disappear last time we talk we kinda of got mad at eachother and he never called again... I've texted him and called him and even left him 2 voicemails and really wanna talk to him should I call him or just forget him
