Infidelity and trust

I met this girl in Feb 2012 and we fell in love.We were so great together upto the time a weekend before her birthday i broke up with her i had been sufffering from emotional stress.She really loved me and she was hurt and i regretted the move and i asked her back and we were back together after a week.Littlle did i know she was now seeing someone else.I only got to know it when the guy was now pressuring her to move in with him i then confronted her and she confessed she was seeing him and they were communicating over the fone as the guy is in a foreign.I loved her and i was really hurt but i took her back.She promised not to do it again.She then left the country to visit her sister but before she left she gave up her virginity and told me she wanted me forever.Things were going on well as she was away but we had fights here and there where i could lose my temper and she would end up crying over the fone.After about 4 months she came back and upon returning i intercepted a message she was texting her sister on how she had enjoyed some company of another guy who kissed her on the night she returned home.I confronted her with evidence and she said sorry but i was so angry and hurt that i broke up with her.But she begged me to take her back she even called my sister and my mother and apologised to them they all accepted her apology but told her the final decision sorely lied with me.after some deep though i realised i still loved her and took her back and we are back together.But the memories are taking much to go away its been a month today since i read the text messages.Do you think this relationship is still worth it or we should just call it quits.She blames herself for all she did but she told me she got scared with how my temper flares at times and she even considered leaving me something which i admitt myself i got a weakness.

you need to give her a another chance and see from there .
