Momma Issues

A little background: my mom has always been a narcissist. She and I have had a rocky relationship since I came out at 15 because she had a hard time grasping the "lifestyle" due to her religious background. Her and FH have had a rocky relationship as well because of this.

A couple weeks ago, I graduated from college with my bachelors (finally!!!) and her and FH got along surprisingly well. Something in my brain told me to wait for the other shoe to drop, because with narcs, it could all be a façade.

Turns out I was right. Yesterday, she was texting me about a family friend having a birthday party for her baby. This somehow turned into her bashing them unprovoked because they didn't ask why she didn't come to the party. Then, she started talking about how they're so unreliable and to count them out of attendance for the wedding. Then, she went on to say that matter of fact, *nobody is going to come to the wedding* because its "so far" (most of my family is in NY and NJ, I recently moved to FL) and not to invest so much time and money into it because nobody will show. Lastly, she said that her and my dad have been having marital issues and to be careful with what I'm getting myself into. She seems to think that because her relationship is failing, mine will too.

I'm gonna be honest, I'm *really* sick and tired of her projecting her insecurities on me. Anytime she sees me happy and accomplishing something, its an issue. I moved away from home, it was guilt trips during the weeks leading up to the move. I graduated, she's telling me I need to get my Masters. I'm getting married, shes saying nobody will come and that my marriage will fail.

What would you guys do if you were in my situation? I'm at my wits end. I'm trying not to let her plant doubt in my mind about my special day, but its hard out here.

EDIT FOR CONTEXT: I'm almost 29 and FH is almost 30. Thank you to everyone who has offered such kind words and positive thoughts!
