TITLE: Me [20M] and her [20F] newleyweds, possible cheating? Or am I paranoid? Urgent help needed
POST: I will try to make this quick because I need to make a fast decision. My wife and I have been married for three months. We both work full time but she gets home about two hours earlier than me most nights, but for me it varies a lot. It's a 30 minute drive home but sometimes I get off at 5, other times I stay until nearly 6:30 and don't get home until 7.

I got a text today on my lunch break from her saying to text her when I am about to head home from work. I replied saying that I would probably get off at 5:30 tonight, she replied saying to text her when I am getting in the car to go home. It's nearly 5 now and I haven't replied. I keep getting this niggling thought in the back of my brain that she has another man over, and she wants me to text her when I am going home so that she has enough time to get him out of the house and hide the evidence.

It's not that I think that my wife is a cheater, but my parents are divorced because my dad cheated and it basically ruined my childhood. So even though I think it is a small chance that she would do this the ramifications of her cheating are huge. I am trying to think of why she would need to know the exact minute I get home but everything I can think of is nefarious.

Do I text her? Don't? I told her 5:30 earlier, I could take some of my work home and leave at 5 tonight, that could catch her by surprise and confirm my suspicions or settle my fears if it's nothing. Please help, I am so new at this and I feel like I am already failing at marriage.
TL;DR: 
Wife wants to know the exact moment I am getting in the car to go home, I could get home 30 minutes earlier and surprise her, bad idea?
