UK visit visa to get married rejected [closed]

I am a Moroccan. I met a British woman in 2013 and we decided to get married. We thought everything would be easy. She started working in a shop for 8 pounds per hour.

Then I applied for a UK visit visa so that we could get married. We had already made an appointment for the marriage at the UK Registry Office. My visa was rejected, although I have a good job and good savings.

We have a daughter who is now 2 years old and I have seen her only two or three times. She doesn't really know me, although we sometimes talk via Skype. I also applied for a visitor visa to go see her and that, too, was rejected. My British girlfriend is pregnant again with our second daughter and I'll be in same situation as with my first daughter.

I'm going to try to apply to Ireland for a visitor visa and, because there is no border from there to the UK, perhaps I will get it and be able to see my second daughter when she born.

I have received Schengen visas four times without any problems so that I've been able to visit with my girlfriend and daughter.
