He won't like you?? This is honestly the last thing you need to be worried about at this point. Horses don't think like we do - a good smack and pushing around may be exactly what this horse needs. I honestly think you're being too nice to him. Kicking at you is extremely disrespectful and should never be tolerated. If he was doing that to an alpha horse out in the wild he'd get a kick he would never forget and probably wouldn't question his dominance again.
If he kicks at you when you send him forward, try making him back. And I mean back - a couple steps away from your direction doesn't count. The videos of you see of Parelli or Anderson the horse is sent forward with just a simple cue from the trainer and responds perfectly is definitely possible but your horse needs to respect you first. Get after him if you need to. Don't worry about damaging your relationship. He'll be much happier if he knows you're the alpha.
I wouldn't continue working with him without help from a trainer. Unless you understand why groundwork makes them respect you, you shouldn't be doing it. Groundwork/lunging is amazingly effective but only if you know what you're doing.
