Crazy title right? I know! Ok ok.... I WOULD LIKE ALL OF YOUR COMMENTS AND OPINIONS ON THIS.....so for Christmas I went to my boyfriend's house, (at the time, we were on a break, now we're back together) and I saw his mom and we exchanged gifts, got her a gift card, something NORMAL, and nice... well she gives me a box, an engagement sized box, it was a red velvet one, and I opened it, and in there was an engagement ring.... there's NO denying that it's an engagement ring... so I took it and said it was beautiful, which it was, and put it in my purse and later left in complete shock... so I get home and my mom asked me what I got and I showed her, and my mom was FURIOUS, asking why and how this was appropriate for her to give me.. and me, always giving ppl the benefit of the doubt, I said she probably didn't mean anything by it, since she likes jewelry, but LADIES, WTFFF would this mean? You really want me for ur son that bad?is she lowkey gay? Idk?!!!
