I have a friend who has been staying with me for a few months. He has a dog, who also stays here, cause well, theyre a package. However on Friday he left to visit his daughter and said "I'll see you in a bit", and never came back. 

I was going to say something the next morning asking why he never bothered to see if it was okay, but I remembered tht he was visiting his daughter, and thats probably where he still was. So I left it alone until this morning when I had finally had enough and let him know I was quite upset that he had been gone so long without his dog and never bothered to check in or see if I had plans. 

This started an argument about how he didnt think he had to and he was with his daughter so he assumed it would be okay. 

I said it would have been okay had he taken 2 seconds to text me to let me know what was going on. Again he said he didnt think he had to and he would watch my dog if I left. I told him I wouldn't just leave without saying anything or checking in out of respect and responsibility. 

It just continued to spiral from there and during which he kept bringing up that he was visiting with his kid and I should be more understanding. He insisted on bringing his daughter home to her mother from his moms because I made him feel bad so he was going to "fix it". I even told him that i wasnt telling him to to come back, but i was telling him that i was displeased after not hearing from him since friday. 

So, am i the asshole because I got upset my friend left friday to see his kid without his dog and never messaged to check in to see if it was okay?
