A few things are becoming more clear.
First, I believe I am called to marriage, as indeed almost all adults are. This does not, however, mean that I
will get married. I do not control that. It means that I will not be too afraid to walk (carefully) with any respectable man through the process of finding out if we should someday marry. I am not big enough to destroy my life through a "wrong" decision. Nothing can separate me from the love of Christ.
Second, I believe I am called to fellowship appropriately as a sister with all my brothers in Christ. This means that I will not fear the emotional results of an appropriate amount of friendship with single men (see above). We are not made not to hurt. We are made to grow like Christ. Naturally, the process of discerning the proper level of friendship is frought with peril. All good things are. I need not force it; friendship comes (or not) with time.
Third, my main focus must always be my relationship with and responsibilities to God above. I must answer to Jesus in eternity, and to nobody else.
