Am I wrong?

Jessica
Trying to figure out if I am in the wrong or over emotional. Me and my SO don't live together though supposedly he plans to move in. Anyways he spent Monday night with me and Thursday night he said he would be back yesterday but his mom had him cutting trees down for her she is 80 well he decided not to come back over because he was tired and I understood that. So he said he would be over today around 12:30 and instead he made excuses and ended up not coming over at all. I knew this is how it would be Thursday and I even asked him then if he was spending the weekend with me and he said yes. I would have understood if he didn't want to but because he said he was I expected it now I just feel mad and sad. Am I wrong for feeling like this. I guess it's the expecting him to be here then being let down. I feel unwanted when he does stuff like this and makes me feel like when our baby comes he will still do this crud.
