Something don't feel right?

I'm a friend of an ex-girlfriend of mine. We dated off on and off for over 4 years. Always broke up over stupid shit. Well, last night was by far the worst. She blew a gasket because I hearted a female friend side by side picture of her weight loss journey. I've known this friend since we were in kindergarten. She's a lifelong friend. The girlfriend didn't approve either way. Well, we broke up and stopped talking altogether. I had moved on. But on June 4th of this year, she messaged me out of the blue asking for help moving her things out where she was living because her current boyfriend had become an alcoholic and was mentally abusing her. I agreed to help but before I could, she went back to the guy. We stopped talking again. Not a week later, she texted me again. This time she was done. I was at work one evening when she went to get her things. She found him unresponsive and barely breathing. He had overdosed on her diabetic meds and insulin. He passed the next day. We have been pretty much talking, texting, or together ever since. She has told me she loves me only as a friend, that the romantic feelings went out with that picture I liked. Everything has been awesome up until this past week. She's just been different. Snappy and too herself. I was deleting some old Facebook profiles I don't use. I saw a guy on one that she was talking too right after we had split up. They talked for about 2 weeks and stopped talking. I asked about it. Said I see you and so and so are friends again. She went apeshit crazy saying I was spying on her and other bullshit. Said she was gonna block me on FB but hasn't. Then 2 days ago she accused me of stalking her because I asked her roommate's son if she was home from work. She has just been odd lately. I don't know what's going on. It kinda feels like she's not wanting to talk anymore. She needs to tell me because we've talked about getting a place together.. Your thoughts folks.. Anything's appreciated
