MY FH and I have been together for 4 years and will be married shortly after our 5 year anniversary.
His family was super warm and inviting to me in the beginning, but as the years have gone on I have felt more like an outcast, than a member of the family.
FH was married and had a child prior to us meeting.
In Nov 2018 FMIL had family come from out of state that I (and my daughter) have never met. She sent a text to FH stating they were going to have a family dinner and he let her know that he was going to be busy with work and would not be able to make it...later that evening when his son called to say good night we found out that FMIL had invited his ex wife and son to dinner, but did not reach out to me.
I let FMIL know that it hurt my feelings to be left out and she BLEW UP and did not come back to our home until Christmas.
Fast forward to our engagement Sept 2019, his mother "forgot" to congratulate us in person until a week later, even though she saw us 2 days after....she also asked FH many times (while I was out of the room) if he was "sure that shes 'the one'"..which I understand, he's been married and had a messy divorce, but still hurtful.
His grandparents have not congratulated us either, but they are constantly on facebook writing comments to his ex wife saying that they miss her.
Family is so important to me so it's hard not feeling loved or welcome.
