If example you confessed your love to a person and he/she say ," Let's be friend first?". What does this mean in your point of view?
(P/S: You guys are already friend but not quite long)
It means they're not into you and that's the excuse they came up with to avert a difficult conversation, doubly so since you've already been friends with them for a while. If there was a chance of it working they would have suggested dating instead of being friends; the whole point of dating is to get to know the other person and see if you work well together.
They're probably trying not to hurt your feelings because they like you as a friend and don't want to have a difficult conversation that's going to leave you upset. This is seriously misguided on their part and personally it really irritates me when people do this; I don't like people jerking me around and wasting my time and I'd much rather they just be direct with me.
I'm gonna give some advice here. A major mistake that a lot of (usually younger) people of both sexes make is not being clear and upfront about things from the start. It's difficult to do because it's awkward, embarrassing, and can often end with you feeling like crap if you get rejected, but it's something you really need to do. Be clear from the start why you're getting close to someone or they're just going to see you as a friend and it's going to get awkward if you try to turn it into something else.
You also need to not obsess too much over any one person that you're interested in. If you let them know from the start that you're into them and they didn't reciprocate, just move on. The odds of them spontaneously developing feelings for you are so low that they may as well not exist and you're going to waste a lot of time for what's eventually going to end in heartbreak for you (unless you're perfectly fine being "just friends" with them and seeing them with someone else, and let's be honest, you're not). You're only hurting yourself by trying to pursue something that's not there. Move on and you'll find someone else you're interested in eventually;
trust me, there are at least 4.5 billion other potential candidates, you'll find
someone if you keep at it.
Also, don't let someone take advantage of you. Try to keep a clear mind and don't let your feelings blind you from the signs of a bad relationship. Being in a relationship feels great and you're not going to want to think about the signs of trouble even if they're super obvious and everyone around you sees it. Keep your head and be proactive about problems. Listen to advice, even if it hurts you or makes you angry. If you have good friends, they'll be there for you and if they give you advice, it's because they're worried for you.
Above all else, though, respect yourself and don't let people jerk you around. You're worth more than you might think and you owe it to yourself to be happy. Don't let someone try to change you. If you want to improve yourself in some way, go for it; that's great, but do it for
your sake. If someone can't love you for who you are, don't waste your time; there are countless others out there who will. Be strong and don't waste your time on people who don't respect you.
