Being single & pregnant

Ok so me & my child's father are close friends & really kinda scared to get back in a relationship because we don't want it to be forced but I kinda wanna make things right and want us to try it out again cause we were together for almost 3 years big been best friends for 5 ! I really do love him but us not being together & not really trying to at the moment especially since I'm im school an hour and a half away and I wanna have sex & talk to other people but since I'm pregnant can I ? I mean what am I to do?
