My father wanted to marry me with Shighaar marriage, I made a vow to observe Sawm (Fast)

Question 2My father wanted to marry me off to someone by way of Shighaar marriage (exchange of daughters or sisters for marriage with no mandatory gift to a bride from her groom). I made a vow to observe Sawm (Fast) for nine months if this marriage did not take place. As the marriage did not really take place, do I have to fulfill the vow I made? I was fourteen when I made the vow and I had not started to menstruate yet. Also, I doubt whether I had other signs of puberty at that time or not. I observed Sawm for a whole month and then stopped. Do I have to fulfill the vow or not? May Allaah safeguard you! Al-salaamu `alaykum wa rahmatullaah wa barakaatuh (May Allaah’s Peace, Mercy, and Blessings be upon you!)
