Should i wait? i feel he does not love me anymore?

i have not been honest with my bf for quite a long time, i kept to myself my inability to bear child, when i finally told him this last year, everything changed, i felt his love changed, he doesnt tell me anymore his plans & whereabouts(he used to tell me eveything b4), i even caught him txting with this other girl which he admitted he had relationship, he came back to work abroad without clearing things between us,he told me he himself does not know what to do, he rarely communicates to me now, but he still does,once in a while, without the "i love you" phrase, he used to tell me, should i still wait for him or is that the clear reason for me to forget him and move on with my life?
