Venus in Gemini... Trine Saturn

My boyfriend has his Venus in gemini in 8th house, which I have read on the internet that it indicates inability to commit to one person at least mentally. However I see that his venus trines his saturn. I was wondering if this would make an impact in his loyalty as a part of a romantic relationship.

His moon is also in virgo and ascendant in scorpio. I have been extremely insecure in this relationship and I don't know if I should hold on to him. I am also a newbie in astrology and I do not know how to interpret them together. Would appreciate the help

Venus is in 8th house and joined closely with Sun. Both are in the star of Rahu in 2nd house. Saturn is also in the star of Rahu.

Rahu in 2nd house shows many obsessions.

Mercury, Venus, Sun in Gemini denotes multiple.

7th lord Venus in Gemini denotes multiple partners.

There is no Jupiter aspect on Venus.

Saturn is in unstable star ruled by Rahu.

These all things indicating that the native cannot be trusted.
