What do you guys think i should do?

Ok. Let me start this off like this. Me and My ex girl broke up about 3 months about. I still am madly deeply in love with her. But she dont know if she love me no more or even likes me any more We been out two times The 1st time it was really my fault and i was busy with alot of things and didnt really pay attention to her That was my bad She wanted to get back with me but i wasnt so sure I decied to give her a second chance. But this time she cheated on me I felt like the world fell apond me I loved her so much i forgave her. But ever since then she been confused and hasnt really been payin attention 2 me. I fell her pain now But she has told me before to let it go She says she is not worthy for me But to be honest i cant let go and i never will But all i want is to be with her I been havin alot of emotional breakdowns and i dont know how to even go on I been tryin for 2 months to get her mind straight and to give me another chance but she doesnt really know what to do what should do
