I came home from work last week and DP was on the phone. Usually trust him 100% and didn't hear much of the conversation, but for some reason alarm bells rang. I checked his facebook the next day and he's been talking to his ex, told her he misses her, loves her, would be back with her tomorrow. I haven't done anything about it yet. Not sure what I should do as I honestly believed that we were happy together. Every time that I go to mention it I loose the bottle to do so. My head is in a bit of a mess about it and I just want to burst into tears all of the time. I have always known his fb password but never felt the need to check it before but had a gut feeling. I know they don't actually see each other (due to distance) and it was obvious that this was the first conversation (not that it makes it any better). I'm just very confused at the moment. Also feel like an idiot for not doing anything about it.
