I want to remain anonymous…… It all started du

I want to remain anonymous…… It all started during our school days, I met this girl in our year 1 and we started dating, we became fond with ourselves that we can’t do without each others, the bond grew to the level that we stayed together from year 2 till we graduated….. I love her so much that even when I don’t have money, I go extra miles to make sure she is okay, I also assisted her with school activities like assignment, attendance, textbooks etc, you know the stress of dating someone in same department with u, in my school we sort some courses, I literally sort for two… I typed this girl project from chapter one to finish and printed it for her… When we graduated, she was having some issues, I met with one or two persons and cleared her, she graduated, now time for clearance, I didn’t her clearance for her because she was busy, I bought NYSC kits for her because I really wanted me and her to go to service together….. we were posted to different state, then d unimaginable happened, she went to camp and during documentation she met a guy, since then things changed, she came back to meet me after camp, promise we will be seen once once as she will be coming to visit because our state is not too far from each others, we are both in eastern part of Nigeria…. Then I notice someone started sending her money weekly, because her alert mail was login in on my phone, I ask her she lied that it’s the elder brother……. After several insistence she open up that that it’s her colleague that she is covering for, later i discovered it was a lie and she ask me to let her be, that I should avoid her……. Now she is telling me I should move on that she no longer feel good around me

I have hit her before because of her infidelity in d caused of our dating, what’s should I do in this case, I love her so much that it seems I can’t do without her
