Relationship matters might be tricky for you in life. Early conclusions on any one person may go wrong as per your aspirations. You need to spend time in one relationship for fairly long atleast 4-5 years before you can be sure about that person.
Next 2.5 years untill end of year 2024, if this current person stays in your life and you are fine with him as suitable partner. You can be sure of him in 2025 and take a long term decision.
My advice for you is to stay with current partner and develop the relationship for next 3 years, mostly it will whither away and can't stand the test of time.
Clarity will be better for you in year 2025.
Rahu - Ketu in 1-7 house axis makes partners unavailable or brings distractions with time. D-9 also has same pattern.
7th house lord going in 12th house with 8th lord saturn can bring tendency of dissolution in matters of 7th house and make partner unavailable in longer span of time.
Saturn - Rahu dasha isn't favourable but Saturn - Jupiter dasha becomes favourable for matters of relationship.
