What am I doing wrong? (Advice Appreciated)

A little background, I'm a guy might be average in all areas. The thing is; been through an heartbreak recently 1 year relationship, pero walang sinabing panget about sakin more like assurance ang atake but she can't stay with me.

The main problem is this is the same scenario with my past ex of 3 years before her, hindi ko alam san mag i-improve dahil wala namang sinasabing areas where I lacked off and talagang ngayon lost ako, ayun lang insights are appricated...
