Looking for some advice

Me and my ex split up over 2 year ago due to him being verbally abusive then one day actually pushed me so I left. I live in a little village about 30 mile away from any of my family, I stayed here to keep my son near his dad as at the time my ex's family were still really supportive. Even after we split. However since I met someone else and im currently pregnant none of them speak to me. I get hassle from them and my ex all he time and it's getting unbearable living here. I just want to move close to my family ad I currently have no one. My current partner lives near my family too. What are people's thoughts on me moving with my son? It's about half an hour away, one bus ride. I'm not stopping him seeing him he can have him weekends and in holidays. I have talked to my son about it and he wants to move as long as he still sees his dad. I'm just really torn. No bashing please just want some advice.
