I guess this is a wedding AIBU question.
This is a tricky question because there's a lot of context here... I will try to be as brief as I can. My relationship with my parents was difficult as a child, they were neglectful and threatened me with abandonment and used shame as a controlling mechanism. Unsurprisingly I didn't do well at school and had a tough time in my teens. They were / are reasonably wealthy so I never went hungry or lacked "things", but there was no love or affection and no physical contact ever. As an adult I drifted apart from them and experienced a great many MH difficulties etc.
In recent years (now 42) I have been through therapy and come through the other side. Now happily engaged. Meanwhile I got to a place where the relationship with my parents was better, helped by my work in therapy. I could manage myself better and learned that I am not responsible for their behaviour. By no means is our relationship close or loving now, but it is polite and respectful and looking forward I am accepting that they will never be the loving parents I dreamed of but I am happy if we can rub along okay. This is the best I can hope for.
Last year out of the blue my parents offered to contribute financially towards my wedding as my fiancé and I had delayed it to have time to save up. I was surprised, but they said as they are very traditional they had felt it was their duty as the bride's parents. Initially I declined their offer, as I felt uncomfortable about it. However my sister, and my fiancé both felt I ought to accept the offer. My sister said after all they had put me through I might as well accept as they had made the offer, it would make them and me happy, and they could afford it. My fiancé was wonderful and didn't pressure me either way but I could tell he was keen to take the pressure of us financially. I discussed it with my therapist also and he felt this might be my parents way of showing love in a weird sort of way. So to cut a long story short in the end it was agreed I would accept the offer but mark out some firm boundaries. I explained to my parents that I did not want a traditional wedding, and although I was grateful for their offer I did not want their involvement in the planning (I worded it much more politely than that but that's what I said in essence). I said this was the reason I wasn't comfortable about accepting their offer as I didn't want to feel obligated to them or that i had to involve them in any decision making. My parents said they understood that am very independent and that they would not expect to have a say in the wedding planning. And so it was agreed on that basis.
Fast forward a year and my Mum and Dad have said that if their names do not appear on the invitations they will be upset.... (They have also started making their thoughts known about some of the guest list, what to wear and where to stay on the wedding night etc). I have already explained this is a modern wedding. We are not having traditional formalities, (getting married on a beach in casual clothes) so no father of the bride speeches or being given away. The invitations will be in keeping with this and fairly modern and simple. I don't want the wording to say my parents are the hosts and I'm not interested in those traditions. I realise that they have financially contributed, but given the context, and the agreement we had I feel I am justified. There is a big part of me that feels they are crossing boundaries and that I need to put my foot down. However, as ever they have also managed to install shame in me. They always controlled me as a child and I feel this is what they are trying to do now.
Although it would normally be tradition to include the bride's parents' names on the invite, am I justified in not doing so on this occasion?
