A few weeks ago I split from my BF of 2 years. It was his decision not mine (no big reason just things not working) and I still care about him deeply. I know I should go NC and I haven't seen him for about 3 weeks but modern technology makes it difficult to cut off completely. He's part of my extended group of friends and so i don't want to block him on FB etc because we are still going to have to interact regularly and I feel i should be able to be quite grown up about this.
The problem is exBF is good mates with another female friend but they have also always been quite flirty (well she's flirty with everyone). I've taken to watching their online statuses to find out if they're interacting. Over the past week or so I've noticed that they are both on Facebook regularly at the same time and for the same length of time. And my mind is going into overdrive with jealousy and the feeling that I've been replaced. I know the answer is just to stop looking but it's like an addiction. Can some sensible MNetters just knock some sense into me please.
