Relationships-when to move to the next stage?

How long do you think it should be before you take the next stage in your relationship, eg buy a house, get engaged. i have been with my boyfriend for 3.5 years and we live together but in my house (he wasnt ready to buy one after 2.5 years together so he went and bought a property by himself). i now wonder if im in a relationship with a man who will never wanna commit, but i just dont know if im being over sensetive to the situation?? why are relationships soo confussing??
Answer
Love is never confusing how long you going to wait for your boyfriend to change?hes never go to change,so time for you to evaluate what you want in your life and go get it but know it wont be with him. you can find anybody better if you allow yourself to do so.
