Search Results: get him to stop being so clingy

So a guy I've liked for a while started texting me a few months back. I did him a favor - no, not that kind of favor - at work, and he got my number from my manager. He originally texted me to say thank you, but things sorta escalated from there. We started talking about our families, past relationships, and soon, he called me "cutie" and "beautiful". But after those first 2 days or so of constant messaging, he stopped. Since then, months later, he has gotten a new phone and told me in person to text him my number. I'm just so confused, because I don't feel like I was being desperate or clingy through my messages, but he just backed off really fast and I don't want to feel rejected again. In person, he's shown me many signs that he likes me, like offering to do things for me (at work and outside of work), he always has a huge smile on his face when we're talking and always looks me directly in the eyes, he blushes so hard, too, and my manager told me that she thought he had a crush on me, so I have a feeling that he might. Why would he back off so quickly? What should I do? Please help! :)

Me and my guy friend fought and we stopped talking. I tried talking to him 5 times but he refused to. He is niy ignoring me due to fight though. It has been over 7 months since we fought. I am stuck. I really can't move on, knowing that I never got to confessed my feelings. I dont expect from us to talk again or he should like me back, but I can't move on because my whole life I am just gonna regret never telling about my feelings. But confessing means I gotta lower my self respect, because he might think that I am being clingy. But honestly, I don't know what else can I do to get rid of the pain.
