Do u think its normal for me to feel this way?

Am going tru a divorce,its been 15 months since we planed to split and now am dating a guy am not in love with him but am comfortable with the thought that he is in my life coz he keeps my mind away from the pain. I try hard not to think bout my past and the situation am in,but i feel lost and betrayed and feel like i will never fall in love again even though....What must i do?
