<human>: Alright, so here it is. Me and my boyfriend are 17, young, whatever, I know. We've been together for almost 6 months now. Anyways, He had moved away for a while and I only met him when he got back last June. We got together at the beginning of December. 

Since he was generally new to where he moved to, he could lie about anything any no one would know. Since he's gotten back down here, I can usually spot his white lies; saying he's seen a movie when he hasn't, just really stupid, really small stuff like that. Well anyways. Him and I have a joke about him having 'another girlfriend' I know he loves me very much, but when he says that he would tell me if he cheated, or if he did have another girlfriend, I have a really hard time believing him. What should I do?

Can you give me a shortened version of the text?
<bot>: Boyfriend of 6 months tells a lot of white lies and I can't tell if he's ever being honest with me.
