I know it's due to my low self-esteem and depending too much on my girlfriend but I really need some advice how to deal with my awful emotions sometimes
So first of all I'm a girl dating another girl, we've been together for over a year. My girlfriend is bisexual and it makes me feel really worried, I get insecure over it, I get jealous at EVERYTHING to do with guys, guy celebs she likes make me angry and sometimes I feel such an anger and hatred towards men because of this insecurity and fear about her bisexuality. I'm constantly questioning her and hurting her over it, she's told me she prefers girls, she loves me and wants me and I believe her but my fears get too strong sometimes. For some reason my mind can only see the negatives and not anything positive, I even feel like she's lying and prefers men because it just seems to me she's way more into handsome men, she likes a lot of male singers, she uses them as her twitter picture icons/headers, there's lots of little things that just scare me that she might like them more :[ But she says she doesn't think of them in a sexual way like she does girls. But no matter what she tells me, I'm still terrified. I actually hate it, I can't seem to accept it and I need help. It's gotten to the point everyday I'm visiting her tumblr and twitter worrying if she's posted guys, when I get angry and shout at her about it and she says "What's wrong with me finding a guy handsome" It actually rips me apart to hear her say she finds them handsome. I feel sick, I cry everyday, I can't deal with it. How do people deal being in a relationship with a bisexual? I feel like my insecurity has turned me into those man-hating lesbians.
This insecurity is the same towards her friends, I full on screamed at her because I read tweets of her joking around with friends, I can't stand her being close to others. I'm just petrified of her leaving me, I'm petrified of her falling for someone else or me being not good enough. I know it's ALL me and not her, I'm the possessive insecure one because I'm worried of being alone and losing her because of my attachment/abandonment issue. But my actions are making it far more realistic that I could lose her and I need it to stop. I know people are going to say "Learn to love yourself then it will all stop" The thing is I've tried, I find it so hard to love myself and feel secure, and yeah I can keep trying to build security for myself but it's so hard and there must be some other way I can let go a bit from these horrible emotions in the mean time? It's obsessive torture. She's left me so much times over it and she says she's never felt so hurt and ruined by anybody like she's been by me and my awful mental illness. I've hurt her so badly she's not even sure if she loves me anymore and she's distanced herself emotionally, I'm hanging on a final chance to change my ways, I don't even deserve a chance but I need to change I have therapy but it's not working.
