<human>: Since my divorce 4 years ago I've avoided relationships like the plague. Instead I focused more on FWB and FBs. My best friend, let's call her Sheila, knows pretty much everything about my sex life, except for what has happened in the past month. Sheila has a daughter of 19. Her daughter gave birth to her son a few months ago. Let's call the father of the baby Jared. 

Now to the complicated part. Jared broke up with Sheila's daughter a few months ago. About a month ago Jared started making passes at me. Apparently he'd had a thing for me for years and I just never knew it. At first I said no friggin way. It was never going to happen... Yet, when someone seems to really like you and persists eventually it starts to make an impression. Jared made an impression on me and, despite my better judgement, we hooked up.

From the first time we hooked up there was something different about Jared and I knew I was screwed. According to him he's been doing everything he can to get me to fall for him (he says he already felt that way). So, I started to see him in a new light and over the past month we've moved beyond a typical FWB situation. In fact, for the first time in years I could see myself in a typical relationship. Everything about the situation is wrong. I don't like younger guys. He's the baby daddy of my best friends daughter. I've never even considered him an option before. Still, you can't always help it when your head and heart say two different things....

So now I feel like I'm stuck between a rock and a hard place. I don't want to lose my best friend but I can't figure out a way to tell her that this won't destroy our friendship. I don't want to lose Jared because it's been a long time since I've felt this way. I feel like even allowing this to happen, at all, let alone as far as it has, makes me a terrible person. Is there anyway to salvage this cluster fuck I've created?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Hooked up with my best friend's daughter's baby daddy and caught the feels. Now I don't know what to do without screwing everything up and losing someone I care about.
