In terms of love life, due to some past attachment, you are either not willing to move on or consider new people, and even if you are considering, memories of the past are not letting you start anything new. You feel unsatisfied when it comes to love, and you do have many options but it might feel like a futile search for you right now. My suggestion is, for you to first heal from any past trauma and remove mental blocks you have regarding love.
Those who are already with someone, you may be going through some friction, detachment or simply distance. Patience and perseverance is the way to sustain the relationship right now.
