My ex-husband is accessing my laptop remotely to sign into my outlook email account. I know the sign in was not me, but it has the IP address for my laptop as the IP used. I signed out of the account at 6:40pm last night from the laptop and today I see a sign in attempt at 11:17pm using my IP address. The location is not far from me, but it's not my home. How can I catch him, have proof it is him? And stop him from doing it? We are separated and he is stalking me, obviously.
