So lost on what to do

[riom]

So Im going to sum up the whole story as best as I can. A year and a half ago my mom found out my dad was cheating on her. This turned my world upside down, and my mom came to me me about it. For the a longest time I had to hear my mom cry call my dad a number of names and just live through this whole thing right smack in the middle of it. I was dating my gf at that time for about two years and I have a problem were I keep these huge personal things to myself(working on it). I did however eventually tell her this was happing and why I was acting different. The way I was acting diffrent is I was neglecting my gf not doing anything special for her anymore pretty much taking her for granted. Well this went on for a good year and when she tried to bring it to my attention I just blew it off honestly I didnt realize how bad I was neglecting her. About two weeks ago she meets some new guy who of course sweet talks her and what not and breaks up with me to be with him. This of course crushes me and I go through that whole not knowing what I had until I lost it. It really woke me up to what I was doing to her and while I love her I had no idea I was being such an ass. She has told me she felt unloved and that she felt I didnt have time for her anymore. I do however love her to death and see the errors of my way and want to do everything in my power to make it up to her. She however has found this new guy who lavish her with gifts and gives her all the attention in the world. I know she left because I took her for granted but I really love her and miss her and want to make it all up but I dont know what to do anymore. I lived with her for the longest time and I feel empty without her.
