<human>: Provide a brief overview of the text.

My cousin(25f) just got engaged to a man(25m) she's been with for roughly seven years. They seem super happy from my limited contact with them and I'm happy they're happy. We haven't spoken since my grandfather's death five years ago. We were close in childhood and by childhood I mean 11 and younger. After that we found our own friends and branched out and went in very different directions. I'm not bitter and I'm 99% sure she isn't either.

The reason I'm posting is because we aren't close and actually haven't spoken or seen each other in five years. That's kind of a long time for people that live less than ten miles from each other. I just don't want her to feel obligated to invite me to her wedding. I fear the family, mainly out mutual aunt and grandmother, would pressure her in to it. I'm actually pretty estranged from that side of the family (father never made us visit much or made it seem important). Weddings are expensive and we are by no means close. How do I let her know that there will be no hard feelings if I'm not invited? Send a  facebook message( I don't even know her address or phone number)? I really don't know how to tell her that it's okay and not to feel bad. I mean, of course if she actually wanted me there I'd go but, we are basically strangers. Thoughts?
