As I'm sure you're learning, owning horses isn't always magical... especially in the very beginning. Sure there's that moment of awe and disbelief that you own one of those amazing creatures, but it's not always like that...
Personally it seems you need to set some boundaries with him... His "lovey"-ness my not be love, it may be dominance. Is he rubbing his head on you? Walking up to you or nuzzling you without you inviting him to? That's not love, it's dominance... Personally, this is how I've dealt with the issues you're having with every horse that I own; When you're going to catch your horse, make him want to be caught... I'm not big into treats, personally... but if that means you giving your horse a carrot after he's come to you and let you catch/halter him, by all means do what works for you. When you're working in the round pen or on a lunge line, don't let him come in just because he turns in and looks at you or asks you to let him stop... stop him when he behaves and he deserves to stop. You want it to be your
idea. Keep him thinking when you're working him too... set up ground poles and/or ask for a change in direction every once in a while. When you go to feed your horse, make him stand away from the feeding trough while you feed. If you have to go into his stall with a riding crop--do it. Don't let him step on you and run you over. One time I was in a very bad situation with a horse who was very aggressive about his feed... he charged me with his ears pinned, teeth bared and had an angry look in his eye... if it wasn't for a swift kick in the chest with my foot, I dunno how far that horse would have gone to get me away from his food. So nip it in the bud while you can! Make him stay away from his food until you walk away.
Now everything I listed above is part of how I do, and have very successfully in the past dealt with and have gained respect with horses.
Of course there's more fun that can be had while gaining respect at the same time! Keep in mind what I'm about to suggest is considered Natural Horsemanship, and some people are very iffy about it... but again, this personally works for me and my horses, it might be fun to try it with yours too; Join Up by Monty Roberts. To do join up properly, you need a round pen. Basically turn your horse loose in the round pen, stay in the middle and ask your horse to trot/canter in circles around you. Frequently ask for change in direction, keep his feet moving and his mind left-brained (the learning side). When you notice your horse beginning to relax, drop his head, lick his lips, ask him to come in... if he doesn't pay attention and come in, get his feet moving again. Keep doing this until he joins up with you. A successful join up will mean your horse follows you in the round pen everywhere you go. Of course, allow your horse to rest in the middle. Give him lots of hugs and kisses and tell him he's a good boy. He'll feed off of your positive energy and that'll be a big reward and even an eye opener for him.
Join up is definitely something you don't want to do everyday... personally, I've done it twice with my mare... once when I had recently got her, and a second time when I hadn't worked her in a while and had lost some respect.
Everything I wrote works for some people, others it doesn't. However, this is just my personal opinion from past experiences.
Hope I helped, even a little!
