"Only in Dreams never in reality"

in addition to that, what you will feel if your boyfriend will tell to you "oh my..?? you are expecting that i will marry you?"""  or  "you know what? I am not going to marry"  or  "someday you will find a good husband for you" or etc etc..... Maybe these words are only some examples how to re-prase the term "I don't like you to be my wife"...... 

Try to talk to him considering your age that ....its time...ist time to settle down...He can always support his family even he is married with you right? But if you will control full his salary, that will be different topic...

Goodluck
