should I leave my husband after a year of misery?

I’ve been married for a year, and everything was perfect before the wedding. He was loving, caring, and excited for our future. But after we got married, he completely changed. He barely speaks to me, gets angry over everything, and when I try to talk or ask if I’ve done something wrong, he shuts me down. Six months in, he admitted his family was influencing him negatively—telling him I was ruining his life. He never stood up for me, and I wasn’t allowed to defend myself. The worst part? He said his ex was better than me and has been messaging other girls. I’ve tried everything to save our marriage, but now I feel like I’m losing myself. Should I stay or is it time to walk away? #relationshipstruggles #marriagedoubt #selfworth
