We broke up 2 months ago and she started dating a guy a month after our relationship ended. Last 2 months of our relationship was hell and hardly any good words were said the last week of us texting. Now it feels like I'm hanging on for nothing and I go a couple weeks or days having tolook her up on instagram, ( its private so can't see anything). When we were together it was great. We even had goals and planned our lives together.. Our families thought we were going to get married. At first I thought this was just a breakup and we'll end up back together but last time I talked to her I hardly even knew her because she was being so cold. I don't know what to do? Any suggestions?
