I think your incredibly strong !
What about internet friendships?, not dating...
A relative of mine was in a similar situation, left with 2 children, felt very trapped and lonely as a male with many responsibilities.
He began talking online to a lady who also had young children, now hapily married.
Another male friend of ours was cheated on by his wife with a neighbour, she was physically abusive to him, he was so ashamed by this.
She left him and shacked up with the neighbour in plain site, did,t give a shit.
He thought he would not meet anyone he was so shy, lovely bloke, totally humiliated by her, felt like he couldn't even go out.
Anyway, long story short he became friends with a woman on line discussing their heartache of both being cheated on.
She lived some distance from him but after many many months they bit the bullet and met halfway in a very public place, it was night time.
They married last year, what he didn,t know was she was incredibly wealthy and had buisnesses in America and the Uk.
He now spends half the year in LA and half the year Uk, before Covid.
His ex wanted him back but he never looked back.
I was so happy for him but what I,m trying to say is sometimes you loose hope.
He said that his mind was closed, could not see any future, he was broken. He also said he wishes he had opened up to new possibilities sooner but he lost confidence, only by having friendships with people in the same boat could he feel understood.
There are many lonely people out there.
I hope you can start looking forward to the future you deserve it.
