This may be scattered and all over the place, I have been thinking on this for a while and finally decided to get some advice maybe. On mobile while the kids are having naptime, forgive any errors please. TL;DR at bottom. 

My Great Grandpa(GG) recently turned 89. I am 29, turning 30 very soon. All my life I was the "favorite" grandchild of his, but I am pretty sure its just because my Grandma, (who raised me, and whose Father GG is), took me to hang out with him so often. But even if that was the reason, GG and I always had a good relationship. 

I have always been bigger then other kids and people my age, but it wasnt until maybe the past four years that I have slipped into the probably obese category. (I am not really wanting any advice regarding that, I know my issues there.) Between heavy depression, lack of care for myself, being content in a happy relationship, and PCOS, I have quite a bit of extra weight that is a struggle to lose. (But I am trying one pant size down this year! :3) Before this bit of weight gain, even though big, I was "fat in the right places" big. My GG used to creepily call me "Hot Momma" whenever I hugged him in public... Which was often as he always invited me out for lunch and dinner. I also spent a significant amount of time just hanging out with him at his house too. 

But once I got properly fat, he stopped inviting me out as much, and whenever I would stay at his house he didnt really talk to me and just sorta acted awkward for lack of a better word. He would quickly finish dinner and be off to his "man cave" rather than socializing like he used to. We always go over to his house for Christmas, and for 2018 Christmas he decided to not give any of my family presents. (Husband and 15 year old daughter, as well as me.) I didn't say anything at the time, but all three of us sorta had our feelings hurt as he had made sure to give lots of other people presents, but somehow forgot us. 

This was relayed to me by my Grandma later:
My Grandma asked GG if he had given me a present, and he grumpily said "No, and I didn't give daughter or husband any either." He then told her that he didnt like me being around as much "since I got fat" because I make him, my 89 year old Great Grandpa, "look bad" and I am not "hot" anymore. 

Once my Grandma told me about this I was livid and my feelings were so hurt I almost felt nauseous. I haven't said anything to GG as he's mostly deaf and really doesn't listen to me anyways. But since then... I have had no desire to go see him. I feel guilty about not doing it, I know he's old and doesn't have long but I just can't stand him at the moment. 

TL;DR 
AITA for not wanting to visit my Great Grandpa anymore after he said he didn't like having me around since I got fat and am no longer attractive in his mind, making him "look bad" in public? 


Thanks in advance for any advice. I need it for sure.
