You know, when I read your post, I truly feel for you.
You know, it seems to me, she has no clue, as to what she really wants. You also mentioned, you're picking up her lies, in a very short amount of time. Maybe she has some kind of issues with relationships or just being honest and upfront with people? It's just my opinion.
My daughter dated a guy similar to her. He was actually dating other females and lieing to her. She caught him, MORE than on once! She also found out, his x was pregnat, again, with another child! I told her that she needs to confront him, in a calm manor
and just tell him the gig is up! She did! She moved forward from it and, in time, will find somebody that she truly desirves! Just like you will! You will find somebody that apreciates everything you do
for them, without any lies. Just remember, you DO desirve a kind, loving, and honest person!
