I have been with my DP just over a year. It was all very positive and intense in the beginning, he told me that he loved me on our second date (I know)
We met on OLD so had been talking for a while before meeting.
Anyway, it was all moving very fast, very quickly. There was talk of us moving in together, I have one DS 10 and he has 3 DDs. We spoke about logistics and how it would work, he was buying a house anyway, due to having money from the ex marital home and had been renting for a while.
We chose a house, completely fell in love with it, but unfortunately it didn't work out. Another house comes along, he goes ahead and buys it.
In the mean time of this he tells me that I now wouldn't be moving in at the time he does. (I'm renting too, my ex lives in our marital home which is being sold)
This was a big shock for me as it came totally out of the blue.
So I digress, we put things on hold about 4 weeks ago, I was feeling unsure about the whole thing, but we have still been keeping in contact daily.
He now wants me to decide what I really want. I know if I stay this will be it, marriage, possibly have a child together (I am totally 50/50) He can sometimes be a bit cutting with his remarks, is quite arrogant, but is very honest, reliable, fit AF, funny, kind, trustworthy, decent, a great dad, tidy 
I just don't know why or how I cannot make a decision.
Any wise MN folk willing to offer me any sage wisdom please?
