this girl i been in relationships for about 4 month called me childish. it started when i got jelous and doesnt talk and moody, i was totaly needy. at the end of the day she text me saying she's sorry for whatever wrong she's done. then the next day i acted like nothing happened but she started calling me brother. so i decide to freeze out, but she still text me whats up everyday. but its different, she doesnt return my flirts like usual, doesnt get needy to me like usual
im confused, what now? how do i get back like we were before?

Buy her a bouquet of flowers and make out. Everything 'll be cool.

you made her feel guilty for making you jealous which is not a good thing because she'll befriend you rather then see you as more. my advice on to fixing things is wake up the next morning and believe you are a new man, you will not be a crazy jealous boyfriend, you will not be a whinny little girl, keep some space but not so far from each other, appreciate your friends and not need to be with her so much and know everything shes up too. that's step one, step two is have a sense of humor and you will think before you react(that's how common sense is developed). if you're funny be funny, if you're smart then be smart, be spontaneous and think of adventures you can both be apart of. build that attraction again, be yourself, and have a sense of humor(very important) and develop tougher skin. and if you're good with your hands then that's always a plus too. believe you are a new man and you will act like a new man. and if all goes to shit, write down on a piece of paper how you feel and then try to explain that to her and don't ask stupid questions you know the answer to.

this girl literally gets me food, pay for my stuffs, does my laundry, and cared every small things.. and i had to make her fell guilty. fuck it, i think i just apologize and i dont care the outcome as long as she's happy

If you are truly Il Duce, then you never apologize.

Then again, the Duce also said that the household makes a girl into a woman just like the army molds a boy into a man. So in this case, you better go to the end of the earth to keep the girl who does the household for you!
