I moved in with my boyfriend like after a month of seeing him
I know not the BEST IDEA but I just knew it was right, and we have been with eachother for 3 years as well as living together.
You and your bf have already been together for 4 years..So I dont see why it wouldnt work out. I would think living with your bf is easier than a roomate... but thats just me. I am not the best person for advice bc I just go with the flow
I would say go for it and see what happens.
