I'm going to confront my friend about feeling excluded
Are there any other concerns you have with your friend?
Well I am concerned about him not including me in things
It makes sense to be upset about not being included in your friends plans. Maybe talking to your friend about why would clear things up on why this is happening. Either way, talking about the situation is much more healthy then lingering on it.
I just feel angry and confused about why he is doing this. My friend said he loves me and then does this.
I am sorry that he keeps doing this. He should want to include you in the things he does. If talking doesn't work, maybe you need to start making other friends.
