Search Results: boyfriend keeps lying

im not sure why my boyfriend keeps saying this to me
so first of all, i have trust issues due to my past (ex boyfriend cheated on me)
so I've been with my boyfriend over a year now
and when he says things like
"babe i can't see u tonight coz my boss told me to work night shift today" or similar to that
i would get pissed off and automatically think he's cheating on me or avoiding me
so i would reply to him like "are u sure? are u sure you're not lying to me?"
and he would get pissed about it and says he's not lying and then would say:
"i know u probably thinking i have someone else but i dont. im not interested in anyone else. im not looking for anyone else. i dont want anyone else. im not interested in banging someone else. im here, im already committed."
but he always says this whenever i think he's lying or if he sense that i dont trust him
do you think it can be lies when a guy says that?

Yesterday he called me (as usual, we always talk on the phone at night) and he asked how I am and all that. So then he asked me "so what did you eat today babe?" And I said "oh.. its gonna sound so bad... I ate KFC today" and he said "what? Again? Thats why I can't see your belly button. Stop eating KFC. It was never like that.. I used to can see your belly button"
And i got offended by this.. means that he thinks im fat right?
and i replied "I dont eat it everyday!"
and he said "you said few nights ago? or last week? you shouldn't eat KFC often. Do you want to have a heart attack or something? Do you want to die before the age of 30?"
So then i tested him even more (i didn't actually eat all of these)
so i said "what the f? ofcourse not! .. I haven't eaten KFC in a while.. so what? I had 2 burgers, large chips and popcorn chicken"
And then he said "hmm.. you should have called me to eat one of the burgers"
And then i got pissed off and said "we talk tomorrow" and hanged up on him
But few mins later, he kept trying to call me and i kept ignoring his calls and then i answered on his 4th call.
Does this mean he thinks im fat? It means that he's not satisfied with my body right? If this is the case, why is he still staying with me? And still tries to talk to me?
Thing is, he calls me everyday, he tells me he loves me everyday and he calls me beautiful most of the time as well as pretty and cute. and we are sexually active.
Plus, we have been together almost a year
So is he lying about loving me and saying im beautiful? is he not attracted to me anymore?
Should i leave him? Im so annoyed by what he said to me
