Our first baby

My boyfriend and I decided we wanted to have a baby.when we found out that i was pregnant he was delighted. I'm now 9 weeks pregnant and he cheated on me. He said he didn't know if he loved me anymore had had been feeling like this for the last 3 weeks he said he didn't know how to say it because the scan was coming up. I didn't see a bit of it coming I still love him to bits and want to be with him i but can't help feeling completely useless.
