Hi Lobs,

I am so sorry that you are discovering this not so cool side of your girlfriend, hugs
Like I said to you privately, I think we don't get to really know someone until a few months have passed. I think three months is very soon to make such a big decision, namely: engagement. Have you thought that she may be an emotionally unstable person? Last night I watched a Lifetime movie (I know, cheesy, but it is a good example, :P). In the movie there was this wonderful girl who met a guy online from a different state and she behaved like the "perfect girl next door". However, once the guy proposed to her, she knew she had him and started showing hostility and violence. The guy was so in love, that he didn't pay attention to those actions as red flags. They got married, and 6 months into the marriage the girl had stolen his identity, drained his bank account and was gone for good

Be careful Lobs, there are many sharks in the sea.
Hopefully this is not case, and I apologize if my words are too harsh, I'm just trying to tell you to open your eyes and be careful.

Best of luck!
