Where to pick up.......

So, some interesting things have happened over the last few weeks.
First off, Saturday, Jorge pushed me to go ahead and go to Atlanta to spend the night with my mom, the kids and with my 12 year old sister who was celebrating her 12th birthday. He hasn't even had enough trust in me lately to even let me go somewhere by myself. And to let me stay the night by myself....in another city. Just weird.
So, we fought all evening Saturday night on the phone. Then when I tried calling him throughout the night, he never picked up. Finally, about 4am, he called to say that he had been asleep and accused me of not calling him. Who knows.
So, I spent the time over there and started heading home. For some reason, things didn't seem right. I started thinking about some of the stuff that Jorge has been doing lately. He has been shaving on almost a daily basis-whereas it used to be once a week to week and a half. He has been constantly watching his weight, what he eats.....so on, so forth. I started making myself angry and started crying.
When I got home, I found out that Jorge had ironed some of his nicest western clothes, shined his cowboy boots, and put on his cowboy hat. This is very weird for him to do. He can't even take out his own damn work clothes. He has never cared about having wrinkled clothes. I've been asking him for months to take me out dancing......when we go out to eat, I ask him to dress up and he says it's not important. He always wears tennis shoes, jeans, and a shirt-usually wrinkled.
I started letting this stuff swirl in my head.......it's just not like him. So, he pushed me to go stay by myself, he didn't answer his phone all night, he shaved, ironed his nicest clothes. So then I ask him what he did, why he ironed. He said he didn't know, he just felt like it. When I asked him where he went, he said to the cingular wireless store. I asked if that was it, and he said yes. When I sat staring at him, he said that he did go out to eat, at a Mexican restaurant. I asked who he went with and he said by himself. He went to this Mexican restaurant where there's this girl we always fight about. He's always looking at her.
So, he dresses all nice, shaves, is all alone-not risking me seeing him, and he goes out to eat at this place where he knows I hate taking him, even while I'm there. I don't even know what to think anymore. When the details of my affair came out, he told me that he always had the chance to cheat on me. He would tell me that girls would always talk to him but he'd ignore them.
I don't know what to think. Maybe I'm just being paranoid. I just feel that he's been acting too weird lately. He hasn't even cared to have sex with me, he just hasn't been interested. I'm worried that he's up to no good. I can't help it. I have reason to believe he's doing something. Whether he's just looking, trying to look good, trying to impress......or if he actually has somebody, I don't even know if I want to know. I don't know what to do. I feel like I'm supposed to stay here, even if he cheats on me. Like I owe him one. I can't stop feeling this way.
I haven't had time to mention anything to him though....with my mom getting ready to go through a divorce, moving in with us......that hasn't helped me in my situation.
I've practically ditched my friends, just so I could stop and try and figure things out for a little while.
