i believe she was also considering you previously, but then after you divorced you really seemed more eager to hangout with her?
made her pause and think, and sorry to say she decided not to pursue forward and only be friends.

why? well, you just got divorced. still too early to jump into another serious relationship. ever heard of rebound gf/partner? she obviously dont wanna be a temporary/rebound partner.

after some time, when you are more level headed (in terms of relationships) then i think you might have a chance.
She might not wanna be a rebound partner, hence she pulls away now. because she wants a serious long term relationship, and i believe you have a better chance then.

also, after the "stop text" she still go out see you? well simple, she already say she sees you as friend.
she doesnt want you to proceed being close to her if you want to be more than friends.
you proceeding to invite her out shows that " OK, i understand your "stop text" and i agree with being just friends and not to proceed further ".

Because i believe she values the friendship, and if u dont pursue more, she is OK with being friends if u ok with being friends.
