Is this suspicious? iin?

I would bet money that he is cheating.

Why would he waken you up though?

Sound more like he was up to something illegal.

hate cheaters... if u cant trust him leave him, look how many people there are in the world, jesus dont subject yourself to this. sorry but i hatebshady people. he woke you up probly so younwouldnt follow, or call, or investigate. so he could be like "baby i told you where i was going what else did yu want me to do" its time to invade his privacy, for he has laid eggs of doubt in your brain. all is fair... find out what happend, then, dont tell him you know, *ask him questions that you already know the answer to, just so you can see what he answers like when he answers the truth, then ask him about that night. Most liers cant tell you what happend from ending to beginning and if you ask them what heppend in between one of the steps they cant recall befause nothing is there to recall if its a lie. most people are uncomfortable to lie and obvious. and i think its normal to be suspicious

If I were you I would ask him about it. Trust me, assumptions will eat you mentally alive! The brain is smart but also self destructive because sometimes it will believe what wants too without the incident actually happening.

It could and could not be that he cheated what not, communication is the key in a relationship, ask to have a talk with him, not as bf and gf but as good friends. And try and put him in your position so he can understand it from you perspective before he goes off in one as men often do when being questioned.

Key point: remain calm if he flips out. Be the mature adult, he may be angry and /or irritated because I guess questioning someone regarding 'trust' issues it quite offensive and disrespectful at some level. So, no matter what happens remain as calm as you can. If he acts very angry torward it and VERY defensive than something may be up, usually I have noticed with my bf before that, when he did something wrong and I would confront to him about it he would be quite defensive, he would be quite angry and loose his temper, but when i feel insecure abut something and ask him, this is when he has done nothing wrong, he is so calm, and says, you can look a my emails or go through the phone if it will make you feel secure.

So m observe his reactions, you know him better than anyone else so you can notice if he is himself or not if you have been together for a while.

Good luck

Your post doesn't even make sense. It is literally incomprehensible without making assumptions that aren't at all clearly indicated and even then there are still huge gaps.
