OP dumbs Old Bro for Hot New GF said because he’s getting in the way

My friendship with Dave- he’s been my mate for 15 years, we’ve been through some shit together, and he’s always been my most solid friend. He’s always been prone to get jealous around me with girls and whichever women are in our lives, either separately or together, he will get very weirdly competitive. However, for various reasons both of us have been single pringles for longer than we’ve been in relationships, but he’s honestly like a brother to me. He’s been a shoulder to cry on when my mum passed away, I helped him buy a house, he bought me my first dog, etc.

My girlfriend Safia- I’ve known her since last November. My gym buddy had been pushing me to meet her and despite me not really wanting a gf, it happened one day and we hit it off big time. I’ve known her 6 months and I can tell you right now she’s the fucking one for me.

She is never in a million years the type of girl I’d go for. She is completely out of my league. Lip fillers, makeup obsessed, runs around making friends with cats on the street, loves pink anything, calm as anything, has a degree in biomedical science, works for an organisation that advises the bloody NHS and is sharply intelligent. When I introduced Dave and Saf to each other I was sure they’d love each other. But nope. Despite me thinking Safia is the most interesting fucking person to walk this earth, Dave has been nothing but hostile to her and is openly rude. She first took it well and privately I apologised profusely to her. Asked Dave wtf his issue was and he called her a bimbo, vapid, etc.

Since then it’s progressed into him openly calling her blondie (she has dark hair), him telling me she’s after my money, him telling me that I need to break up with her because she’s only using me and someone like her would never want to be with someone like me. Safia has said literally nothing about him, and I know she has an insecure streak where she feels like people don’t like her as it is, so naturally I’ve stopped seeing Dave as much.

He’s called me drunk last night and told me how I’ve let a ‘loose pussy get in between him and I’ ... I’m honestly done with his guy. Am I doing the right thing by severing this relationship? In the last 6 months my life has been getting better and better- and coincidentally I’ve been seeing him less and less. Him disrespecting my girlfriend is the nail in the coffin as far as I’m concerned, but my other friends think this is a classic case of me being caught up in a shiny new relationship and not seeing the bigger picture.
