Waiting for my SO to wake up and I'm bored! So why not blog?

I'm trying to decide whether to unfriend someone on facebook....care to decide for me? This is an American married to a Malian who I met ONCE in Mali. She was really strange in person and told me all sorts of weird stories. She is bipolar, or I guess was, because she told me that some traditional Malian medicine cured her. Anyway, she moved back to the US and friended me on facebook.
She is one of those people who posts constantly, like 30-40 posts per day. She had a baby who died about 2 hours after birth and then she had a second baby who is now a few months old. 1/2 of her posts are pictures of her daughter, which doesn't bother me. She's cute and those are easily passed by. She reposts a bunch of random pictures from some group pages about childbirth or she'll repost her other friends' pictures of her kids, which I find strange. She actually did this to me once, took a picture off of my page (of my daughter) and reposted it on hers. I immediately messaged her to take it down, which she did. But I was still really bothered by it. She'll also post a bunch of "congratulations" posts. Like "CoNgRaTs to my BESTIE so-and-so for being preggggggers!!! WIll it be ***team PINK** or *team blue***?!

So there you have reason number one why I'm thinking of deleting her. Whenever my pregnancy becomes known on facebook or if I post baby pictures, I am worried that she'll repost my pictures or, at the very least, write status updates about my pregnancy and/or baby.

Reason number 2? Well, because she lost her first baby, she is constantly posting things about miscarriage, still-births, and infant loss. Especially right now, because she's trying to rally people to sign some petition about infant loss. So everyday, my newsfeed is just plastered with infant loss sayings, statistics, quotes, pictures, etc. I am not naive, I know that there is a small chance these things can happen. But I also want to have a positive pregnancy and I don't want to be bombarded by infant loss.
She also has a FB album with 200 pictures of her 1st baby, after she died. These are full on, close-up shots of the baby and make me really uncomfortable. She reposts this album almost every month or makes photo collages with the pictures.

So if it that was my only issue, I would just hide her. But I also fear her over-sharing about my life. Which is why I'm thinking I'll delete her. I know she'll notice, because as she said, she stalks my facebook all the time because she misses Mali desperately and wishes she still lived her. So she'll notice, and probably message me, and I may have to give an excuse.

Okay, that was really long and I'm going to go finish doing my little one's hair. But I'd love to hear your thoughts...defriend or not?
(ps. I shouldn't even be saying this but one of the reasons I have hesitated to defriend her in the past is that she is one of those people you love-to-hate. She writes these crazy long rants which are pretty entertaining. And she'll make weird statements like, "I am so happy that I wear hijab now....of course, for Allah, but the number one reason is because I used to spend so much time on my hair. Now with my hijab it's sooooo easy!". haha uhhh what?!)
