點做好?幫下我

其實我認為你應該跟她去一些不是只是談天的地方， 例如做運動或看戲，先讓她不會覺得跟你在一起很悶（很多時候分手的原因也是因為一方覺得悶），順便了解她的興趣，初期避免去那些重點是談天的地方，例如cafe，這些地方之後去也不遲阿。 ：）希望能幫到你

多多陪佢啦，同佢儘量關心下佢。或者帶佢去睇一D比較開心D電影啦。
食下野啦。岩岩失戀D人差不多都系甘樣啦。

the first thing is, why does she go out with you? is it just because she wants to have a boyfriend? i am asking this because i don't think anyone can recover from the last relationship so fast and start dating another person so soon. before you two go dating, she should have know that you are shy sometimes. if she really loves you, she should tolerate you personality. i don't actually think it is your problem. if she wants to talk, she can start a topic to chat but not complain.
but of course, if you want to change your shyness, i guess you can talk to her about her daily life, like what she is doing recently, any special things happen, etc. or you can tell her things happen around you, better if they are funny so the conversation will be happier. if you don't have courage to start a topic suddenly, take her to a movie, and after the movie ask her about her thinking and feelings towards the movie. then you relate things she said to different topics. so the outcome will be you have a lot to talk about but you don't have enough time.^^
i hope this can help, but i really think you should figure out why you two are together.

請佢吃放題、自助餐、打邊爐、唱K、睇3D戲、BBQ、踩單車、去沙灘游水、遊樂園、離島玩......
