Try not to drip feed so bit long
Around a year ago me and DP had a break in our relationship then I started seeing someone else. I really liked him and we spent some time together but I couldn't get over my DP so when the chance to get back together came I took it and now we have a DS together and our relationship is great and stronger then ever.
So now my closest friend has just split with her boyfriend and has informed me she's started talking to the other guy. Now I feel really uncomfortable about this because she's done something similar before and I don't know if I'm just being unreasonable or if I have a right to feel uncomfortable about it. She's always on and off with relationships and none ever last and I always get the impression she slightly jealous of my five year relationship and the family I now have but I don't want to fall out with her over this and I don't really know what to say to her. Any advice would be appreciated.
