Hi akash its going to be ok if u marry another girl, don’t be ashamed of urself. Just forget all that as a bad dream and focus on ur future. Ur current gf know about u that u are not as her and she know that u will going to accept her without considering past things. Don’t be a fool to marry her as u are telling that she still don’t have a constant mind and loves u only in her life. If u think that she is really changed from the past things then only forward to next step.
