I feel as if my SO is cheating on me. Today he had to go in for drill then told me he wouldn't be able to see me after drill because he had to go into work. They are closed on Sunday's but he said they were gonna have to do some cleaning, but his Facebook location says he is in a different county an hasn't replied to any of my messages since 3 an only sent me 3 messages at that today. Now he's not answering any on my texts an now some of them ain't even going through...am I over reacting?..
