It took me a while to realize that he didn’t care about me, just the drug. Luckily I hate meth, it makes me feel like shit. Otherwise I might have gone down the same road as him! I am happily single now. Last time I saw him he looked awful and was still using. But I can’t fix him!
How anyone can blatantly lie this much, especially when it's this poor, is beyond me. >

If I had to guess, it is a mental disorder. I would assume his upbringing was not ideal and he escaped through lies. He had dreams of grandeur and felt his current life held him back. Just on the cusp but never there (picture George grumping the gates outside the school he wanted to attend.) 
It seems almost identical to Anna Delvey. >

I dated a guy who was a meth addict. He was delusional. I think it’s drugs. >

Sorry if this is too personal a question but may I ask why you dated a meth addict? They seem pretty volatile to me. >

I didn’t realize how severe his addiction was at the beginning. >

That’s fair enough. Some people are scarily good at covering up how bad their addiction has gotten. >

Yeah that was actually a big issue for us, he had a job and made 150K+/yr and owned a home, etc and he would throw it in my face that I wasn’t doing as well as him. But his life was a wreck even though it looked good on paper. >

That’s fucked up I hope your in a better place now. People like that tend to blow their own lives up eventually, or drive everyone away from them in my experience. I have an alcoholic parent and it’s a nightmare trying to not let that negativity drown you.
