When to stop trying

My boyfriend has been making me upset the past few weeks and I've been crying and he just ruins my days when I'm excited about something and he's so contrary to what he said earlier and he always makes up excuses not to be with me. Then he gets mad at me when I cancel one plan so I can hang out with my mom. When I tell him my feelings he gets defensive and I try to present them in a calm fashion until he gets upset and starts yelling at me. Am I am in a toxic relationship?
