I romanced Tali before the suicide mission and after the suicide mission, the game let me roam free throughout the game..

If after the suicide mission, i reject Tali, would this affect Mass Effect 3 outcome? If so, is it possible to re-romance her after beating the game?

I wanted to see other relationships thats why i broke up with her..

Help?

Please don't answer by saying "Yeah, i got the same problem" or "I'm not sure...."

Bcause that isnt an answer
