Strange male behavior!-guys answer!!

Ok so everything is finally going good with me and my boyfriend, no problems, and my parents are cool with him and I can see him when I want. But we talk on the phone a lot and I can easily tell whenhes acting different. So the other day he was just...

sitting on the phone and not saying anything and I was like why aren;t you sating anything and he's like I'm watchin tv. Then he's like can I call you back? So he calls me back and still says close to nothing and when he does say something its not in his usual tone. His usual tone is all cute and he's always saying I love you or yes honey, yes baby? Now it was like what? Yea?when I would say I love you he'd say I love you too so fast which he never does! Usually its I lllovvveee you too babyyy! And we do thids thing where we will just ask each other do you love me, so I asked him that and he's like mhhmm! Then I told him he was acting weird and he's like I'm not acting weird you're acting weird!so it made me really mad!so finally he told me something was bothering him and that was that and I thought that he would be normal the next day because he said he was sorry for acting like that and to just forget about it. We usually text each other a lot too. The next day he was still acting weird! But not as much. And then he's like why don't you call me back after work which was 8 hours form then! Then he's like please? He never does that! So for 8 hours I got no texts or anything! When I called him after I got done work he's a little better but acting really goofy! Then he tells me that I'm being rude?! And he keeps saying strange things like are you cheating on me, and then he's like baby I'm just kidding! Then hell say like why don't you do this or that and when I say no he's like fine! Whatever! And then I get mad and he's like babyy don't get mad I'm just kidding! So basically he's acting really strange and I don't know why I never get texts form him for the past 3 days! I mean I know he got new jobs, but even I have a job and I make time to text him! To me he shouldnt be that busy where he can't pik up the phone and say I love you! So guys please help me with this because I don't think girls can answer this one. We planned on living to gether(seriously) and when I asked him yesterday if he wants to live with me because he was acing a bit strange hes like yea. Thats it! No yes baby! I cant wait to wake up to your face everyday!_ like he usually says!!! he was kind of cocky when he was talking abouot his future the other day. I just don't understand how someone can go from texting me ever2 secnds saying I love you and I miss you and calling me on their break to say how much he loves me to no texts no calls nothing! And is acting strange when I do talk to him!

He's most likely cheating on you and pissing you off on purpose so you can end it.

But I would be so hurt if he was cheating on me! He always tells me he would never cheat on me and he never has cheated on anybody because hes not that type of guy! He tells me that he will never leave me and he couldnt ask for more when it comes to me! I went htorugh so much to make everything okay with us!!! Does anybody else think he is cheating?
