After my separation and divorce I did wait to seek out any sort of male friendship or attention (aside from the guys I studied with in my masters program) and several men whom I had know for years in Al-Anon (for families/ friends of alcoholics).
Even though though Holy Mother Church recognized my legal separation (still married and living apart from my husband) and the civil aspects of my divorce the "sacramental" status of my marriage was (and yours is) unclear until the tribunal reviews it and makes a decision.
When we profess our Faith and the teachings of the Church we are acknowledging the Sacraments, and Holy Matrimony is one of them. A Sacrament can not be "undone." We can't undo Baptism, an absolution after Reconcilliation, the Eucharist after the consecration, nor a Confirmation after the Bishop has imposed his hands. Marriage is the same. No one can "undo" the sacrament of marriage, only determine (through the Tribunal) if there was a sacrament there in the first place. If it's determined that there never was a sacrament there is a "Declaration of Nullity." In other words, the church recognizes the legal/ civil aspect of your marriage, and acknowledges that there was never a sacrament.
So, if one finds themself in a divorced situation or state they are presumed married. I would not have sought out male friends to go to dinner with, movies, an afternoon activity or an evening out when I was married because it was inappropriate. Those sorts of activities a married woman does with her husband. I had so many people question me why I wasn't going out with men, and many offers from co-workers to "fix me up" with a lone brother, brother-in-law, divorced male friend, etc. I was so tired of saying "no," "No," and "NO!"
It's a lonely time when you want male attention, someone to attend an activity with, go to mass with, etc. I was fortunate to have a variety of female friends, including some 20 years older than myself and able to attend a concert, a garden walk, etc. It was a blessing during that time.
I pray that you get charitable responses to your question here in the forum. Glad you posed the question.
