My 7yo son is overly affectionate with me (mommy) and I’m not sure how to correct it without hurting his feelings

The title pretty much speaks for itself. I need help.My son isn’t overly affectionate with anyone else. Actually he’s pretty seldom about it unless it’s someone close like Aunty. I’m pretty much raising him alone and I’m his world.I’ve broken him out of sleeping with me finally. But when he does he rubs my forehead when I’m sleep, wraps his arms around me and gives me plenty kisses. He comes and checks up on me he even calls when he’s not around. Love my sweet boy.Well now he’s kissing me every 5 seconds LITERALLY. On the lips, arms, chest wherever he can reach. He wants 1000X hugs a day. (Non exaggerate) I mean he will be eating dinner at the table, STOP eating and come to wherever I am whether I’m all the way upstairs pr not and says he’s needs a hug and kiss. This even happens during sports after school and you can’t just leave practice and give mommy huggies.When I’m sitting down he has to be touching me, even if there’s no room he squeezes his way in where he’s nearly on top of me. Which can be rude, he usually does it most if my boyfriends around. And even he gets a bit annoyed. He even tries to lay on top of me sometimes and GOD he’s big. But it makes me feel weird also, he’s damn near my height! I’ll try to move him but he just comes right back. And I’ll ask him to politely move and he will literally move an inch.I’ve ignored it for sometime which I shouldn’t have but now when we are in public it’s the same. And even still, I just feel a bit uncomfortable because he’s a bigger boy now.I don’t want to discourage his love. I hear people all the time say he’ll grow out of it or it’s just a phase but I’m just trying to show him boundaries that’s all.. Even when I do approach him he’ll say “I’m just giving you a hug” or “I just really love you, you you’re the best”. Complete sucker I am!Yesterday while I was eating my food he was literally weighing on my shoulders. In a nice way, or at least I thought I gave him a brief description of personal space and how mommy needs that sometimes so she can get things done. He says to me, “Ok, I’ll leave you alone for personal space”. And I could see the tears in his eyes while walking away. Yes, I’m a sucker and I ask why the tears? And he burst out in tears and says I hurt his feelings.I’m just stuck. I don’t know what to do. via /r/Parenting http://bit.ly/2F5CZYA
