Should I be concerned?

i just started seeing a guy that i immediately felt was the one for me. I recently ended a fucked up and abusive relationship with my boyfriend of 5 years. I felt a strong connection with this new guy and we have been in love since we met, besides a couple kinda big fights. I’m trying to determine how honest of a guy he is, considering I’ve been extremely forward with my own past, which is checkered. Regardless, I’m extremely loyal and tend to offer too much of myself in love. I keep hoping someone will match me in return but anymore i feel used and abused by the men i choose to keep.
So my question is this, I’m mainly asking those who either have a degree in psychology or who knows what it takes to get one. So this guy I’m seeing that just moved in with me claims he has 2 degrees, one psychology degree and one degree in criminal Justice. I don’t have a degree but i know more than the average person about psychology, and I’ve been professionally diagnosed with BPD. Is Borderline something that someone with a psychology degree would maybe not have any awareness of? He doesn’t seem to have any idea what it is. He’s implying that “Borderline” means nothing it’s a mute condition that exists on the fringe of all or none of the personality disorders. I’m i over reacting when i question his degree? I asked to see it and he tripped out. Is he just telling me lies? I’m scared of getting hurt again, my last boyfriend destroyed me cheating on me with who i thought were 2 of my best friends of 20 years. I’m so tired of being lied to I don't know wtf why! I’ve always been generous and kind and loving, admittedly i can have a short fuse but I’ve never called names or disrespected around other people. Is this guy full of shit too? Or is it possible he’s just not as familiar with Borderline in particular. I feel like he’d know. He’s basically responding to me questioning him with sarcasm and blatantly yelling at me that I’m fucked up. Is it me?
Should I be concerned?
