recent reconnection, but big mistake

So recently I reconnected with a girl on here just trying to be friendly like and everything and I started liking her again but previously we broke things off because she’s got a problem and just not less than 10 minutes ago I’ve been accused of cheating and talking to other women /// well this is SW, and I do have friends here. How the hell would she know I’m talking to other women unless she better fake account and messaged it so I message other women she’s not my girlfriend and frankly now I don’t want her as one. she seems to want to control everything I do so now I can’t even have friends who are female and ask questions. I don’t understand.
