Pls read details and help.
So I have a gf who I love and will always love and we both plan to marry and I know we will marry. but all the sudden the thought "if you were single who would you date" came up in y head and I thought " I would date this other girl" but now I feel bad because I feel like I have a back up girl or second choice girl if my gf were to break up. I don't want to live knowing that I would date this one girl knowing I have a gf. I love my gf more but the problem is I feel like I have a back up when really I love only my gf.
