Thank you for writing about your issues here. I understand that it must be a difficult thing to go through.
As it was a long term relationship, it is understandable why you would like to continue with the relationship if you feel that there is even a slight chance that you might end up getting married. But you need to look at the reality of it as well.
I understand that having hope that you both will eventually get together is making you want to take another chance, but you need to accept the reality that the girl you are talking about does not want to take that chance, and has already made her choice to move forward without you.
Try to look at the situation from her point of view as well, and understand that she has taken a decision after considering everything. I understand that it hurts, but you need to start making efforts to move on from her and live your life. You both had a good time, remember the good memories you made and let her go. You have been on the same page for a long time, and now it is time to let go and move on.
If you need any assistance or would like help in doing so, you can get in touch with one of our relationship counselors on the platform, and have regular sessions with them.
