Just want to rant

Okay so let me first say I love my fiancé with all my heart but sometimes I wonder if he truly loves me. We’ve been together for 2 years but just before me and him were dating him and my best friend dated. Didn’t last that long only a couple months. Needless to say she’s. crazy and really slutty but I love her. She’s always been there for me. Recently she got her nipples pierced. I told her I wanted to get mine done. Then she got hers done. I thought okay whatever. Then she shows her nudes to my fiancé! And he’s like ummm okay. She shows me these nudes as well. She tied up in rope with her toys hanging out to show off her new piercings. Later on In the day my fiancé tells me that if I wasn’t in the room he would have grabbed the phone and gawked at her. I feel so hurt and betrayed simply because he never tells me how beautiful I am. But always tells me how hot she is. Ik he’s just attracted to her body. She’s chunky but not like me. She has curves were I am just a lump. I’ve been losing weight because of personal reasons. I’m already down over 20lbs in a couple months. Which is huge for me. But still he never says I’m hot or beautiful. I can’t help but feel betrayed by my best friend as well. She went and got nipple piercings when she new I wanted them first. Then she shows them to my fiancé. She is constantly starting problems between me and him and I think it’s because she still loves him. And ik I should just stop being friends with her but it’s not that simple. We’ve been through more then normal together. And she like my little sister. But I’m still bothered by her constantly trying to make a move on him.
