If it's any help, keep in mind that our "views" on things such as love and sexuality are largely inherited, cultural concepts.
And cultures change as knowledge converges on them.
Look to your 'heart'. What's best for maintaining human relations ? It's been explored that the monogamy myth for humans is a relatively new idea and the test of time is not wearing well on it.
Trust your heart and put less weight on what the 'culture' has tried to feed you.
