Polls: Guy's Behavior

I suspect a guy friend has feelings for me based on his actions. He stares, gets jealous, observes me and focuses on me, remembers details I tell him, he reads me like a book, knows how I feel (attuned to me), wants my attention all the time, wants to contact me, acts nervous around me, avoids eye-contact up close and sometimes shows me his soft side (sends me songs, and compliments me etc). Other people around us notice it too and have told me multiple times "he likes you".

He keeps asking me what I feel for him, and he wants to know whether I like him or not. But the weird part is, whenever I try to talk about his feelings, he denies it. It's almost as if he gets nervous when I notice his actions. Why does he want to know what I feel if he isn't interested. Don't guys usually avoid a girl that likes them if they're not interested?

He becomes super defensive and says no, but his explanation changes every time. He gives me a different excuse every time he tries to deny it. He already knows I like him, so he isn't afraid of rejection.

I mean, it's fine if he doesn't like me, I'm fine with being friends... but why is he so defensive? Just be calm and tell me "no". What's the big deal?

I'm 35. I am very nurturing, kind, etc. as many have said. I am very successful - a medical office clinic manager & I own my own online cannabis store. I am also very attractive. I turn heads. I get men to do double-takes and stare. I don't wear makeup and my usual outfit is an ankle-length skirt & a professional blouse.

I happen to get interest from ***REAL*** men - older, about 10 years or so, successful in their own right. The norm around here... men closer to my age, 30s to 35s, are more like boys stuck in adult bodies in comparison.

I know a lot of guys say women are only in their prime 20s to 25s.
In my 20s to 25s I was graduating from university with 2 degrees & working in the military; whereas, back then, most men my age were fucking the local trollops (/sluts for Americans)

Me and my ex broke up a month ago
No contact since

He starts work at 5am
When we were together, he would call me before work everyday
So around 4 30am or 4 40am

Someone added my snapchat around that time.. 4 40am
This rarely happens
I usually dont give out my snapchat to anyone
So how did they get my username?
If I do, they would add instantly and I would know who it is

Why would anyone randonly add my snapchat at 4am?
They searched my username
Not by via quick add
So that was odd

Could it be my ex?
Or him trying to get someone to add me?

Me and my former boyfriend were together for nearly 4 years
We were on and off within the last year
But he usually initiates contact and then we would make up and get back together
It got toxic

3 weeks ago, we ended the relationship
When we ended, I got most of my things/clothes and left his apartment
I still had abit of my clothes there though since they're not as important

Its been 3 weeks and no contact from him
But when I came home today, I saw a box full of my leftover clothes from his
He left it near my front door outside
It was so random - I didn't expect it
I expected him to just chuck it out or something

Why did he give it back 3 weeks later?
