should I forget and move on???

Hello..I like a guy who also like me but the problem is he's afraid to be committed....

2year ago we meet on social platform...from there we became really good friends..he always encourages me about my life , family & everything..

Soon we became very good friends & first I realised that I really like him bt I never said that but then he realised and confessed that he also like me but I denied that he's only attracted or just a simple like...but disagree with that and for 2year he's been after me...after 2year when I gain some courage that okay he might not be like other person bcz of I have some past trauma...I realise that I should give my feelings and that guy a chance...so I also confess that I also have feelings for him from the first...he was very happy to hear that and we communicate more with each other in a hope that we can know each other and can take the next step but every time I ask him about our relationship he says that we're more than friends and he can't be committed now because he has many responsibilities and he's afraid from being committed...for this thing we fight..I'm creating distance bcz I have some past trauma he also knows that..but he gets angry why I'm doing this I shouldn't do this we should be like couples in the name of friendship..I mean I feel like a puppet ..

So now my question if he was afraid to being committed then why he has done this things ..I warned him from his confusion but he was like no matter he love even until now...I realise that I love him more then I image ...so what should I really do now ??should I move on??or give him some time have some serious conversations??

Help me to understand please....
