I say it depends on how strongly u feel about her, if u can bare to see the stage(the marriage) tru which she'd be going to break off all that u both had then go ahead.
If its a case where ur only friends now and all the feelings u had 4 her are gone then go youth even if u can't eat with knife and fork, u nuh haffi eat nuttin bring it home, just be there in sense of respect.
In another sense depends on how it went down, u can not go, ,to show her that you really don't even want to see her nor give a crap.
As far a si see though seein as she has gotten involved with another guy, they must have been together 4 a while hence it must have been a while since u and her seprated so u really shouldn't have nothing against her at this point or am i wrong?
