NEED ADVICE AGIAN, PUTTING HORSES TOGEATHER

YOU GUYS ARE SO GOOD WITH YOUR ADVICE I WOULD LIKE TO ASK YA SOMETHING ELSE. I GOT A YEARLING MARE 1 1/2. JUST ABOUT A WEEK AGO, I HAVE FENCED OFF AN AREA FOR HER FOR TWO REASONS, ONE TO GET TO KNOW CORY MY 6-7 YEAR OLD GELDING, AND TO LET HER KNEE HEAL FROM HER TRYING TO JUMP FROM ACCESS DOOR ON TRAILER. BUT ANYWAYS, THIS AM SHE HAD PART OF THE FENCE DOWN, AND STUNG THE ELECTRIC ROPE ALL OVER PASTURE, JUST TO GET OVER TO CORY'S SIDE. THIS HAPPENED AND TIME FROM 2AM TO 7AM (SOMETIMES I HAVE TO SLEEP) SHE CUT HER LEG AGIAN BUT NOT REAL BAD TO HAVE VET COME OUT BEFORE MONDAY. BUT TODAY WE DECIEDED WE WOULD LEAVE THE TWO TOGEATHER, CORY GETS A LITTLE BOSSY, BUT HE SHAKES HIS HEAD AND THE SHE WILL START TO TROT OFF AND THEN THERE HE GOES AND THEY ARE TROTTING MAYBE CANTERING A LITTLE THROUGH THE PASTURE, HE WILL NOT BE NEAR HER BUT HE'LL THROW A BUCK OR TWO. IS HE HAPPY OR IS THERE SOMETHING I'M MISSING OR AM I JUST A WORRIED WART. I JUST don't WANT ANYTHING TO HAPPEN TO EITHER ONE OF THEM.

It doesn't sound like a problem to me. It sounds like horses playing and getting along well. If there were a problem, one of them would be chasing the other relentlessly, cornering, kicking/bitting, constant ear pinning, etc. A little of any of that would be okay while they tried to establish their pecking order. I would worry if there was a lot of the above for an extended period of time, but trotting/cantering/bucking sounds like they are having a nice time together.

If he want to attack her or something you would see it right away. Horses show it VERY clear. Mine run after each other bucking and kicking around all the time (and they are together for 1.5 years already). Both your horses are young (even the gelding), so it's normal playful situation. BTW, be ready to see them --flying-- around at some times: youngsters love to do it.

Hello again!
I wouldn't worry. Horses like being in one another's comany, and hate being separated from a herd. If your gelding is not directing his kicks at the mare, he's probably just feeling his alfalfa and burning off some energy.
Horses show what they think of a stranger right away, they don't hide it and then come out and show their true colors - if they didn't like one another, you would know right away as they would be relentlessly chasing each other around, biting, kicking, pinning ears, etc..
Just keep an eye out... and make sure if you're segregating a horse from another horse to use a solid barrier - horses often won't respect a thin wire fence and can hurt themselves trying to get back in a "herd." They feel extremely vulnerable when they're alone.

Putting new horses together is no big deal, they will always kick and bite but it is a horse that is what they do. I would let her settle in a little and then work on her being alone away from other horses.
