I'm out of town right now and I can only reply in English, hope you don't mind.
First of all, I'd like to say that from my impression (based on those cases and your responses), you both have a long road to work things out and to learn & move towards a healthy relationship. It could be a life-long learning process and so I am not going to give a lecture here : )
In short, I'd like to share with you some foods for thought, hope it may help you a bit.
1) Why men's behavior and response are always hurting us? One of the fundamental reasons is that men and women are different ... if we (women) don't realize and accept the existence of these differences, we will be disappointed and will feel hurt most of the time. To get along well with the opposite sex, we do need to understand them (how they think, how they behave, and why)! There are lots of materials on this topic and I'd like to recommend the book "Men are from Mars and Women are from Venus" by John Gary (there is Chinese version). Read through it and try to understand the male. This will make you feel a lot more easy and change some of your beliefs and paradigms (beliefs & paradigms that were given to you by your parents, your cultures, your friends ... etc but they may be just myths and have not been proven to be correct!)
2) What kind of relationship are you longing for? How have you been treating your boyfriend? Take some time to think thoroughly. We all desire a relationship full of love, care, trust, honesty ... etc. The trick is ... if we want a particular kind of relationship, we have to provide those particular qualities first ... simply speaking, if we want someone to love and to care for us, we have to love and care for him first and to do all these with our true heart. Don't ask for the return, just do it first (do it with true heart!) and you observe what will happen.
3) Do not try to control and manipulate, this will push the men away from us. You had begged and pledged, all these in the eyes of a man are signs of controlling and manipulating, plus these also make us unattractive. If we want to ask someone to do something, we need the appropriate and effective communication skills (and again this is a life-long learning process). How did you ask him to take you home? What did you say? Did you use words and phrases that match with his underneath desire and needs? Let me give an example here: one way of saying is e.g. "I know you are tired but I am pregnant, don't you think that you should show some cares for me ... I feel hurt that you don't care for me"; another way of saying is e.g. "I understand you are tired and I can feel how uneasy it would be for you if you have to take me home, but probably due to the hormonal effect of pregnancy, these days I do feel I need you to be around with me and take care of me, I would feel secure and being protected if you could take me home today" ... you see the difference?There are many other ways of sayings and of course it has to take other factors into account, but I am just trying to illustrate how different ways of communication could affect how a person is feeling & perceiving and hence leading to different responses.
4) your boyfriend is not quite a caring person in deed, but if you want to walk along with him the rest of your life, maybe you need to influence him (note, not control or manipulate) and also to accept some of his flaws.
5) we meet someone who has flaws that we don't like, we can either leave him and look for another better one OR we can take it as an opportunity & give it a try to learn how to love & embrace and to learn how to build a relationship (try, fail, acquire more skills and try again...) ... and after trying, if it doesn't work, then we can either choose to leave or give it another try. No matter what our choices are, we need to bear in mind that we got to learn something from it.
