If a friend did not wish me on my birthday but friends are having a surprise party for her shall I go for it?

[883]

So I have this friend, lets name her A..and she along with a few other friends did not bother to wish me happy birthday and haven't bothered keeping in touch. But whenever its one of their birthdays they always somehow remember me and they always have surprise parties for eachother. Now this friend A and me used to be really good friends but for the past few months she hasn't been in touch. (Before anyone says well I can message too- I used to message initially but then I realised that they just weren't reciprocating it) So yeah I haven't met them for a while now and i'm really debating going to this party because a part of me is really mad at them for not keeping in touch and not remembering my birthday and treating me so shit...but a part of me still wants to go because we used to be good friends. Any thoughts would be appreciated
