Please someone give me some advice 😭

My husband and I had a break from one & other for 3 months as he was making me very unhappy & it drains me being around him, it’s not the first break we’ve had either we’ve been married 3 years and 5 months almost & he hasn’t matured at all if anything he’s got more childish & listens to he’s family way to much & doesn’t take anything I say seriously 😒 it’s soo exhausting being with someone like him I find myself wanting to be with him but then I’m sick of being treated second best all the time to he’s family, I want to move a way from everyone and start it fresh again & he agreed but I don’t no if he’s really ready to commit to it for good or is he just saying it to make me happy witch has done in the past 😕 & want me to move back witch I’m not willing to do anymore , what should I do I’m so confused 🤷‍♀️ he’s good when he’s away from them & where so much happier together but he changes dramatically when he wants to move back it’s like he’s choosing them over me please someone give me some advice im so venerable right now!😭 sorry if this its my making any sense xx
