How can I stop him from being jealous?

so I've been dating this guy for a little over a year now. we have had some problems and a couple months ago, we broke up. I went out with this other guy tyler. but then broke up with him for my ex, steven. ever since steven and I got back together, he's been extremely jealous and controlling. he hates the fact that I talk to any other guy besides him, especially when I talk to tyler. we would get into huge fights about me talking to tyler so eventually I told him that I would stop talking to him. I lasted about 2 weeks but then started talking to tyler again. I told steven that tyler was not a part of my life and I dont ever make contact with him. he always finds out that I am lying to him & really am talking to tyler & he threatens me with 'its over.' and tells me im a liar & that I lie about everything. I love him & know he's like this because he feels hurt & betrayed but what do I do? tyler is one of my best friendds, I could never just stop being friends with him for anyone. how do I tell my boyfriend this without causing chaos between us?

:::sigh:::

well, I can completly see where steven is comming from. But this all has to do with trust. You have to relize that if he cant trust you then things will not work out anyway. And, it does sound like you still have feelings for tyler, if you are truly in love with steven you should be able to put anyuthing behind you and disregard tyler, but you showing that you cant do tha either means that you still have feelings for tyler, or you just want steven to get so mad that he breaks up with you anyway. You need to choose one or the other, sorry if you dont like how this sounds, but steven sounds like an ass anyway because he cant trust you. I would advise you go with tyler, just becasue he isnt controlling and jealous. I want you to respond to me and tell me how this goes! BEst of luck!
