Hi OP
I'm not going to belittle your experience because I think you are right. Men are very focused on looks and if you don't have them you are immediately at a disadvantage. That's just the facts and yes it is unfair I know.
I assume you have tried to make yourself as attractive as possible. I mean I do quite regularly see women who have lovely hair, nice figures, dress well etc but facially are actually not that attractive. They do still seem to be able to find partners. Jennifer Anniston is a good example actually - I never thought facially she was that attractive but she obviously has good hair, figure etc
Okay I'm going to tell you my story and I hope it helps you.
I was 'lucky' enough to be born with an attractive face (small nose, high cheekbones, full lips). Also large chest and long legs although a bit of an apple prone shape so always had to watch for putting weight on around my middle. (I'm old, fat and single now by the way so I'm talking about younger me)
So you are thinking wow, that sounds great and I guess it probably did make life easier in some ways without me realising or appreciating it.
However I grew up in a violent, scary, chaotic household with 2 mentally ill parents neither of who loved me (they were not able to love me). I actually went on to have some physical ugliness caused by my childhood - think body scars and teeth that had to be fixed due to sucking my thumb (traumitised) way after my big teeth came in and so this made them squint/buck. I also couldn't have children and whilst I can't say for sure this was due to my childhood I would think it definately contributed.
At school I was a super well behaved child who worked really hard - the goal being to not make anyone angry and to get good qualifications so I could 'escape'
So yes I did get good qualifications and yes I have had quite a few good, decent looking men who loved me and wanted to marry me. I did marry one but got divorced. However my relationships were all doomed and that was down to me.
Men who loved me and were kind, stable etc I couldn't love back as it felt really uncomfortable, odd and I kept waiting for them to start laughing at me and tell me of course they didn't love me. When that didn't happen I would generally start testing them to try and make them leave. I also have issues with being unable to regulate my emotions, anger issues, impulse issues, an eating disorder. So in short I made their lives miserable and eventually they would break up with me or a few who didn't (probably issues of their own) I would break up with. I certainly couldn't love them.
Men who were offhand with me and made me feel unwanted, not good enough I chased around like a lovesick puppy trying to prove to them I was worthy and desperately trying to get them to love me or approve of me or give me attention. These men obviously reminded me of my dad and so I was obviously trying to heal my childhood wounds of having a dad who hated me (yes he did, he told me and it was obvious anyway)
So like you I have never been with anyone who loved me and who I loved back.
Only in middle age did I get help from the NHS and a clinical psychologist has organised me to get therapy shortly. They refuse to give me a diagnosis as they say it is not helpful but a mental health nurse who I had to see prior to getting access to the clinical psychologist thought CPTSD/BPD. I have to say they both make sense as a diagnosis and they often overlap.
So like you I ended up alone. I actually chose to stop dating about 15 years ago as I was either hurting people or being hurt and there didn't seem to be any way to fix it. I knew by then something was 'wrong' with me but it took me ages to get the right help.
I feel angry, sad and full of regrets. I should have had a lovely life with a man who loved me and who I was able to love back. I should have had beautiful children who I loved and cherished. I should have lived a life where I didn't have cripplingly low self esteem, depression, anxiety, OCD, eating disorders, shame.
The shiny package on the outside did not reflect the inside at all.
I met plenty of other women on my travels who I guess would have been considered 'less attractive' but my god they were all so confident, stable, sorted, calm, kind, normal. Each and everyone of these woman had good parents and dads that loved them.
I am not belittling your experience - I just wanted to give you another story of 'suffering' and not finding love despite 'good looks'
One day I will be dead (you know from old age I mean) and I will be at peace. I will no longer look and expect danger at every turn, I won't exhaust myself being hypervigilant, I'll be able to stop worrying.
I try to think I am on this journey/path because it is where I was meant to be. I don't know why. Part of my therapy is to accept the life I have had even if I am not happy about it.
Your post did remind me of a book I enjoyed and I don't know whether it would help you to read it or not. It was 'flavour of the month' by Olivia Goldsmith. I won't spoil it for you but it's about 3 woman and what happens to them. One of them is 'plain' and is left by a man. She gets plastic surgery and is transformed to being beautiful. She gets him to fall in love with the new her (he does not recognise her) and then what happens.
You will certaintly be able to relate to it I think and it might at least validate you if nothing else.
Sorry OP. Life is not fair. We can only ride it out as best we can and one day it will be over. Hugs to you x
