he doesn’t really like you then… you should dumb him before he dumbs you. Find someone that is willing to stand up for what you believe in. My boyfriend loves that I’m standing up for animal rights. I’m sorry but you should really dumb him and find someone better.
Relationships are all about respect. You could try explaining that to him, and explaining what peta2 is exactly and why you like it. Maybe he just doesn’t fully understand. I hope it all works out for you, and if you do end things with him I’m sure you will find someone who will respect you and your interests!
Kick him to the curb! My friend went through the same experience and I told her the same thing. If he can’t have an open mind and respect your choices, it’s unhealthy to stay in a relationship with someone who threatens to dump you over something you believe is right.
