What next? Life after divorce

I (M29) got divorced last year. Mine was an arranged marriage. Ex-Wife was still contact with her exbf post marriage. I found her with her bf and demanded a divorce. She initially went with her bf, but came running back after he said his parents wouldn’t allow him to marry her. After rounds of negotiations, parental tantrums, we settled upon mutual consent with one time settlement - I don’t mind it, lawyer told me to think of it as past life Karma and get it over with. A year later, I’m in a decent job, nothing fancy, just another ordinary IT job. Did everything people told me to do and all I learnt/read about post divorce. Moved to a new city, solo travelled a lot, picked up a hobby, therapy, journaling, social meet-ups, treks, hikes, biking trips. All done. After all this, still feel shitty, alone and ignored. Extended Family stopped inviting me and my parents because, apparently I’m a bad omen to have in functions. They say it to my face that ‘he didn’t do x/y/z for me (something as trivial as not inviting an uncle first) he deserves it’. You know who your extended family is in these times. Few Friends remain, few show true colors. I don’t miss them or want to keep them. But it’s a revelation and a painful one. Feels like, jumped from a burning ship to a sinking one. I’ve travelled a lot this year. Just spent the holidays alone. It’s moments of solitude like this that tests your positive attitude. How do you handle loneliness.
