Find out what his status is. Try to gauge if he’s open to a relationship in general. Maybe he’s already got his eye on someone. Maybe he’s just had a horrible breakup and he’s not open to dating at the moment. You will need to respect him, his feelings, and the situation he’s in by not being overly pushy if he isn’t in the mood for a relationship. You may try to wait it out, but only if you're okay with just ending up his friend if it doesn't work out.
Act casual. Remember: you can't actually make him fall in love with you. He's free to choose what he wants. Beyond that, though, people can't always control who they love. If it's simply not there on his end, resist the temptation to punish him for it. Accept that if the relationship is meant to be, it will happen; if not, then you're meant for something better.
Advice, never compromise with guys, you only give them control over your life, YOUR life, and they will guilt you and manipulate you and tell you you are a bad person but in my honest opinion and literally the best thing I’ve ever done was to “brutally” put my foot down. It took two weeks because he just wouldn’t give up, crying and saying he was going to kill himself (because I told him a. I don’t care to hear about his “superior” arguments against feminists or black people r anything at all and then b. when I ignored him or get this, DIDN’T SEEM HAPPY when he ignored my request started crying, telling me I became an awful person and how I make him want to kill himself.)
@Eric, ask yourself and please be honest (I know that you like being straightforward) if that woman was indeed the one* (let me clarify the one, wouldn’t want you to think that I am stuck in a Disney Movie ending). The one: being a woman that you would consider as a serious long term partner, that you would be proud to introduce to your family and with whom you could see yourself having children. Would you really risk losing the relationship by blaming not responding to a text because you are busy.
