I'll keep this as short as I can.

Basically upgraded one my plates to FWB 6 months ago, things were going great, dates were awesome, met her family, etc. Considered potential for a LTR with this woman. We are both in our mid 20's

The last week however, her bahviour was a bit shitty and I was noticing some red flags. Seems like she has a lot of guy friends or she enjoys a lot of male attention/ aka needs validation. Not 100% sure on this, still need to analyze it more but I am aware on TRP stance on women with lots of male friends. That being said, this is the only main thing. Seen her Monday night when I caught up with her old man for a beer. She's been pretty busy with work and stressed out lately. When I spoke to her she was vague as shit, then as I was leaving she escorted me outside like usual but this time gave me a kind of cold shoulder goodbye, I just left, didn't really think or say too much about it. Got home, done some shit I had to do and recieved some mail regarding our holiday overseas in a couple weeks. I text her about it letting her know I had received the papers from our travel agent, again she was being short with me. She messaged me a vague "have a good week, enjoy your evening. Goodnight" at the end of the convo. This is unlike her. I just said to myself, fuck it, if you're going to be vague and give me this cold shoulder shit then whatever. (If she is fucking around behind my back then whatever again; AWALT. I'll just walk if I find out) So I didn't even reply to it. Decided to try out a soft next for the first time ever.

Almost been 4 days now, still haven't contacted her. Our Snapchat streak (which I don't care for, really) was about to end Wednesday night. That little fucking sand timer was flashing around being an annoying cunt. She sends me a snap Wednesday night. I get the notificiation but don't check it. I was having too much fun doing my own stuff to care. I forget about it, the streaks ends and I wake up in morning and open the snap. Just a photo of her paper work she was doing that evening with the caption "is it Friday yet?".

Now this is where I need advice. To be completely honest, I was trying to go for one or maybe even a 2 week soft next. However I did say to her on Monday night when I was over at her house that I would try and organize a date with her this weekend because I had some mad ideas before I decided to soft next her. ALSO I just got a phone call from my old folks as it's my sister bday Friday and they've asked me to invite her over as well. I don't give a shit if she comes or it, I'm not the one inviting her and this would be the first time she has met my family which is a pretty big deal for me. So what should I do? Continue to soft next, no contact and forget about her being involved in anything this weekend? Should I invite her to my sister birthday? (In saying that, how would I word it because like I said, they've invited her, not me and I don't care if she decides to come or not considering the way she's been acting). Advice would be awesome!
