None of us can decide if you should continue this relationship or not. It's entirely your decision. But personally I feel you deserve someone who respects you and stays loyal to you. When one partner cheats, it is really hurting to the other. And I don't think anybody deserves to go through that hurt. Having had a boyfriend cheat on me in the past, I just want to tell you that sometimes it is more necessary to look out for our own happiness. You never know what the future holds for you. If you decide to let go off this relationship you might be saving yourself from more emotional strain. Also, I don't really know what the situation with the pregnancy is. But if your girlfriend does decide to keep the child, will you be able to accept it? Your relationship is really complicated and you are really young. Just sit and think things out, You will come to a conclusion for yourself.
I am always here if you want someone to talk to. Stay strong.
