In a weird situation right now. I've been dating this chick since like right before Halloween. She seemed like real wifey material. Good looking, fit, feminine, NO DEBT and she was about a inch taller than me

We were getting pretty heated and i was thinking about making her my girl if the vibes stayed the same. She caught the flu in January.
At first I thought she may be lying and trying to slow fade me(i dont think she is evil enough to lie about being seriously sick but who knows with how women move nowadsys). She wasn't really responding to texts so I decided to give her space. Whenever I do get her to text back she says she appreciates me checking in with her but she still feels like shyt etc. Then one week she finally responds after I check on her and says she's been in the hospital.
Next time I check she says she's been in the hospital for 2 weeks now and had complications with the flu and she was planning on coming home soon because she feels a little normal. This made me think she wasn't lying because only a crazy person would lie and keep it going for weeks to make u take the hint. Haven't heard from her after I asked if she got out of the hospital and how she feels about vday on the 18th since she's recovering and I'm going out of town for my brother's bday. I also smashed a new chick this Sat because I haven't seen sick wifey type for a month and am confused on how to proceed.
I'm wondering if I should feel bad even tho we arent committed, should I keep trying or just move on even though i was fukking with her heavy and she seemed like she was fwm too, if she really is sick (im about 90% sure she is now), how she's going to look after being seriously sick and in and out of the hospital for a month.

sorry for the long post but I've never dealt with a chick to get sick like this
