I know this may sound petty but I'm really upset and confused over it. My boyf has a room in his flatmate house. I feel like he acts inappropriately with her and I have said this but he says it's my insecurities and I should get over it. For instance, he broke his phone a week ago and instead of buying his own he's been using hers to text and call me which means we can't have a proper convo and every time I want to talk to him I have to go thru her. Also he goes and meets her for lunch at her work (he says to use her phone). He sleeps in her bed when she's away coz he says it's more comfortable and when I go round he wants to sleep with me in her bed rather than his own. They go shopping together at weekend and go on nights out together. He says they are friends as well as flatmates. I think it's too much and is disrespectful to me and inappropriate but he says I need to get over it. Am I being u fair???
