My girl has, too, had a love before Solas. Solas may not have been her first, but she loved him deeply and truly, so of course it breaks her that it ended. She's just not going to let it dictate her existence. Before Solas captured her heart, she wasn't actively searching for romance, mirroring myself. She's a humongous sap for romance, and daydreams and fantasizes, but she was also content. She didn't need someone. She may have wanted romance, but not so desperately that it was at the edge of her thoughts always. Solas was happenstance. Very, very welcome, cherished, and wondrous happenstance, but happenstance nonetheless. The breakup wounded her. She cried, she mourned, she hurt and ached, but at the end of the day, she knows she has a duty and that the hurt can't influence her to the point it affects those around her. She took time to grieve, but Cole, and Dorian, and Cassandra, and Varric were there for her. Cole felt her hurt and helped in his own special little ways. Dorian reminded her to smile and live life. Cassandra teaches her that she stronger and braver than she believes, and that doubt can actively strengthen one's faith (whether in a religion or people or something else) if used appropriately. Varric remembers and reminds her that she's a person and deserves to be treated as such. With people like that in her life - with her purpose and meaning to both those in her inner circle and to the general population - she can't wallow in hurt forever. It won't instantly go away; time isn't always an alleviation, but she's learned to live with it, She's learned that there is a tomorrow, and that to make it to that tomorrow she has get up and walk. My decision to do Jaws of Hakkon after he leaves for third and ultimate completionist playthrough will be an opportunity for that character development. It will lead her to a position where she's less woe to this broken heart and more worried about Solas' safety, where he is, is he okay. He better be okay.
I have rambled my thoughts a lot today. And I'm probably late with this but c'est la vie.
