my gf and i has been on and off for around a year now she has 3 ex i have none and it bothers me that she still talks to her ex last time i saw that she commented on his picture and he said some thing about being better than the bf she had now (me) and she didnt stay any thing instead she just had a chat and we've talk about this she just says that its cuz she hangs out with different ppl and for them its fine to stay frds with their exs or w.e what do i do now ? thanks
