Lying or forgetfulness, is he lying or just forgets? Options

I really need some help. I've been going out with my boyfriend for 4 months, he lives with me now as well. His mom is in elctro shock wich kinda messes with her head. He went to visit her and came back all freaking out saying the cops were after him and they had asked my best friend to set him up. I called her and she said that yes a lot of ppl had been busted for stuff, but they weren't even interested in my boyfriend, he had a couple fines from driving and thats it. He still was freaking out and decided he was gonna turn himself in so he could at least sit in jail for his fines. We dropped him off at his mom's the next day and he said he would call if he didn't go in. Well, i waited for a week and when no call came i called the jail. They had no record of him being there at all. That really pissed me off, so i went to his mom's house and found his ex-fiance, the girl he had left for me. He had told me she moved back to IL. Then his mom told me that he was on his way to WA, 2000 miles from here! The next day he calls and can't imagine why i would be so mad, he said he just "forgot" to call me and tell me he's not in jail. He also didn't think his ex living with him at his mom's mattered either. I don't know if he's telling the truth, can a guy really forget that much?
