There is this guy who I have a huge crush on. He knows I like him and we went out once (I invited him). He told me how happy he felt when I asked him out, bought me a gift on the date, offered to visit me when I go back to school (which is a few hours away). After that I got really busy and I was kind of unsure of whether I should let him visit me considering we weren't official or anything so I made excuses for him to not visit and telling him I am busy. But once school break comes, I would asked him to hang out again. We made tentative plans to hang out but then told me that he got really busy with work so couldn't make it. I told him it's fine and that we can hang out next time. Summer break came along and I initiated contact and asked "hey, how are you?" and got no reply. I am really heartbroken about this considering I really like this guy. I suspected that he got annoyed that I got busy and made excuses not to see him. But he could have moved on or found another girl. I have no idea. There are so many possibilities. I don't know how to handle my feelings about this and is this worth pursuing further? I don't want to be annoying and be that girl who keep texting if he has no interest.
