So me and my ex split up back in December/January time due to him going through my phone reading my messages with my friends and family members whilst I was asleep, I confronted him about it and said to him that he got trust issues which he told me he trusted me. He said he wanted to get back with me and then said he wanted to be single. I’ve moved on and I’m currently dating someone who lived not far from my ex, whilst I was over the new boys house my ex messaged me to ask why I was near him which I asked him how he knew. Now I’m worried he’s stalking me or checking to see where I am what should I do?? I was with my ex for a year and 3 months and we was engaged
