OK I had date this guide for 1year we had a good relationship. But on Sunday we were supposed to go out after he get out of church. It was like 2:30i seend him a text message saying "Hey babe. At what time you going to pick me up ?" And he didn't text me back.
So I call him at 5 he didn't answer. And now he haven't call me. I just don't understand that why he event tells me that he love me a day before and then the next day he doesn't talk to me.
Well I don't know should I call him asking for a explanation about what happened Sunday and or should I just move on with my life.
Please help me...

Don't call him. Give him time, he should be the person to call and explain what happened that he didn't call or anything like that, but for now just take your mind of him.

Sounds a little complex. Give him enough time, when he calms down, you can talk with him. If you disturbed him, you need to apologize to him honestly. Ｇｏｏｄ ｌｕｃｋ．
