It’s your wedding, you can invite whoever you want.

Invite whoever you want to attend

View Quoted Comment But I don’t want to hurt nobody feelings and favor my grandma because my grandma always wanted to go to a wedding and bringing her and no one else I don’t wanna play favors

You invite who you want to invite. Period.

We invited my entire mother's side, but not my father's side, because of relationships. (My dad and I are very close, but we are the outcasts of his family.)

Irony: the only blood family member I had at the wedding was my father... because my relationship with my mother fell apart.

So. Invite who you want to invite, this is a celebration of the family you are building.

View Quoted Comment Omg the same thing I haven’t saw my mom side and dad side the family for long time because of the relationship too

Invite who you want! There's no rule that everyone with an ounce of blood in common with you has to be invited. It's your day and you get to have the people you want there (and not have the people you don't want there).

Honeslty it's your decision. Whatever makes you happy and if this make you happy then go for it. Why not

It is your wedding. Invite anyone you want and don’t invite anyone you don’t want. It’s so much less stressful that way.

It's your wedding you can invite whomever you want.

Honestly invite who you want to witness your special day with . If that includes only Grandma then so be it.

It's your day and you should be supported.

Invite the people you want there. People are there to see you two marry, not to talk about the other guests. Do give a heads up to your ushers, or have someone greeting guests tell them, that you would like all family and friends to mix together on both sides , as you are coming together, so should they. It is awkward, in a situation like yours, or where someone from a big family married someone with a small one, if people think family should sit on separate sides, and leave a large section over full, and another near empty.Once told, people from both sides, will be seated evenly.
Unless I have knowledge they someone has been ill, deployed, or moved a long distance, I would never ask about someone not there. I would assume a schedule conflict, not talk about people's relationships with family. Assume the best. If in fact it is the worst, family that cannot get on, that is enough sorrow to the people involved without other people "thinking awful things" and gossiping.

View Quoted Comment Ok thank you. I’m just going to invite my future husband his side the family. But the bridesmaids I never met his sisters in person before

View Quoted Comment You are not required to have any bridesmaids. And if you wish, you can have friends, no family. ( I have 4 sisters, and get along with all, and many close cousins. But had friends as Bridesmaids.)
But if they would like to welcome you to the family, and you would like them as bridesmaids, that is fine. Your choice. I had only one family in my BP ( plus 3 MOH and 2 BM friends.) My Matron of Honor was my grandmother's younger sister, my auntie, who is my parents age and I have always been close to. You may have whomever you want. Even your grandmother. My auntie did not do the bachelorette, and friends and MOG did my showers. Auntie and I went out for a special pre-wedding evening , advice and memories and a special time. You choose which family you will continue to keep close, and which you may or may not see in the future, but do not want in or at your wedding. Your choice, not what other people think, on this one. If you want friends and your granny, and you and groom want his sisters too, they can stand with him, or one with each of you, or both be your Bridesmaids. Don't worry what other people are doing. This is a new beginning , the people you want to carry forth into your future with FI.
