Its a shame that a few nobs have called you a liar there’s no need of it, there’s plenty of support out there and anyone of us would help if asked. It’s always easy for people to judge a situation when your not in it. Harder to see what’s going on when you buried under it.
You have a choice and don’t let anyone tell you other wise. You are treated terrible by someone that is supposed to care your only option is to walk away if some told me I couldn’t marry/have a partner is not worth your time.
