The man vs the women in the same sign can behave very differently. Sag men are very attractive and passionate but I believe(I've heard many others attest to this too) the majority by far are either covert or overt narcs. He didn't ghost u because he wanted an immediate answer u failed to give. He ghosted because he really doesn't want long term although most sag men say this because they are possessive and want u to be exclusive while they WILL cheat. They can come off cool and smooth and other times so passionate. They are charmers and they are EXPLORERS. They feel a need to discover several people in different and deeper ways and will manipulate to get that connection. He sprung this on u the few times he wasn't sure about another woman, and he is with that woman now until he craves to explore options again. When a man is serious about marrying u, he will show u consistency no matter what. There is no family issues so detrimental that he can't keep in touch with the woman he sees as his wife and mother of his future kids. Set boundaries with him. However rigid or flexible these boundaries should be needs to depend on ur hearts capability to entertain his presence with zero attachment because u have known him too long for him to be taking advantage of ur heart like this. It is cruel what he is doing but ur willingness to see that and accept that will require time spent on research on narcs and uplifting urself consistently reminding urself of ur worth. If ur religion brings comfort and roots u in ur identity of a woman of great worth(priceless) then embrace ur religious practices even more, than u will not tolerate anything less than to be honored as u honor others.
