Don't be moved by how nice he is to you.
If you think about it, being good to you should be the foundation, if he is not good to you, then why should you be with him? The love brain is often moved by some cheap giving, and feels that the other party is good to him, so I also want to love him. Actually, being good to you, in a relationship, is the foundation, not the plus. When you fall in love, you must learn to go with the flow, don't be afraid to start, and don't dwell on whether it will be fruitless. No one can say for sure. If you are always afraid of losing him, then you will easily fall into a state of gain and loss, and you will easily fall in love. Someone asked me if I knew that I should start a relationship that didn't work out. I think this mentality is bad because you presuppose failure in the first place. The most important thing in falling in love is not to consider the result, but to enjoy the process, because when the process gets better, the ending can be better. 
Always put yourself first. Consider in advance whether you are happy or not, and whether the other party has taken care of your emotions. Don't study the other person's emotions, if you are always thinking about whether the other person loves you or not, then he just doesn't love you. It's not that you don't want to give, but you have to remember your feelings while paying. For example, if you give, the other party is very cold and ignores you. The love brain will think, it must be that I don't pay enough. People who are not in love will know, then if you don't respond, I will be sad, then don't wronged yourself. Seeing no, this is a normal reaction. Put the future in front of love. Never give up your future for love, such as giving up a better university, giving up a better job opportunity. There is a good saying, go ashore first to kill the person you like. Don't become a victim of love, love is common progress, it is you who meet the person you love in the future, not give up the future for the person you love. Love is about making you better, not dragging you into the abyss. Give up your future, maybe the other party will dislike you very badly in the future, and even think that you are not worthy of him. 
Always ask yourself, how good is he and will make you like him so much? Slowly you will become rational. Don't be deceived by his fantasy, you have to see clearly what kind of person you like. When we are in love, it is easy for us to automatically put a beautiful filter on each other, which will make you forget each other's shortcomings, which is very bad. You have to constantly remind yourself what you like about him and what he deserves to like? If this shortcoming exists, can you really accept it? When you love someone, never forget to look at the shortcomings. There is a saying that look at the disadvantages before marriage, and look at the advantages after marriage. It means that you have to magnify the shortcomings before marriage, see it clearly, and accept it before continuing. After all, shortcomings are basically not going to be changed. Never give up your social circle for love. Many people's love brains are because the circle is too small, so they think about love all day long, and forget that there are other important things in life. By the time you are abandoned, you will find yourself helpless, after all, your friends are gone. With your own social circle, you will get more information from the outside world, and there will be someone next to you to give you rational analysis or advice, you can refer to, you can think, it is not easy to fall in love. And, because you have your own business, you won't be obsessed with love, you won't stare at each other, and you'll be more comfortable with each other. 
Always remember that you can live well without love. Love is the spice of life, not a necessity. A person lacks independence and always needs to rely on others to live, so he will die and live for love. Know your bottom line, once the other party touches your bottom line, give up immediately, don't be soft-hearted. For example, your bottom line is that the other party must not split his legs. Well, when he makes a mistake, never forgive him. Only if the other party knows your bottom line, does not hurt you, and can respect your bottom line, this person really loves you.
