How would u deal with you ex that u still live with talking to someone else?

been together for 4yrs and been broken up for 2 months but still live together cause money is tight but she is obsessing over someone else she talks on the phone from dusk till dawn no lie and it really bothers me to see it, the other girl lives in another state but my ex is on her phone texting and talking to her 24/7 and it bothers me to no end i have asked her to tone it down and its like she doesnt give a crap how i feel at all, how can i control my anger and hurt when i see this all the time. i have gone from loving her to hateing her how do u make some see or understand how you feel without seeming super jealous or crazy?How would u deal with you ex that u still live with talking to someone else?
Well the first thing that you may consider is finding a new place to live. It seems that living together post brake up is not an ideal situation for you to be in and also with the seperation you can move on with your life. However for the time being you can try talking to her once again and just let her know how you feel. But as you said before the reaction you go back was less then desirable. I would just ignore her and do your own things go out with your own friends. I hope this helps
