Ok, ill start from the beginning, Me and dp used to follow each other on twitter until a few weeks ago because he got into an arguement with someone on there.
He unfollowed me and some other friends so this other guy wouldnt target us, (he was a complete fruitloop)
Anyway, i have still been looking at his twitter now and then a few weeks back i noticed he had followed a girl who used to to have a huge crush on him years ago. she caused alot of problems in our early relationship.
At first i didnt worry hugely as she hadnt been on there in nearly a year.
Fast forward to today, and she has been on there and followed him back. it freaked me out so have been checking his twitter all day. just now i had a lucky chance to see his phone and there was a message between the 2 on his screen, not sure if he knew i saw it. so i looked at both there twitters and there is nothing, so it must be a DM.
There has been no word from him telling me hes talking to her so hes doing it behind my back.
Do i say something now
