I think u should avoid POF like the plague. i was inundated with contacts but there is no screening because it is free. i have a close friend who met her new lawyer husband on POF but not until she met some scary people. i tried christian mingle. still guys contacting based on looks only. Was overrwhelming. i then joined eharmony where there is screening and tons of compatibility questions. they send u a few matches per day. no browsing. i met a great guy. didnt work out because we were at surprisingly different levels in a very important area. and members have to be completely divorced or widowed which i like.
i was set up in an arranged marriage of sorts (jw) who after the wedding stole thousands from me and turned out to be a con man. i kicked him out within a yr of marriage (much later than my uber witness parents would have liked. they wanted him out a week after the wedding)
online dating has its perils and u have to be careful but i think it can be a useful tool. limiting oneself to jw's has a high chance of incompatibilities after the fact since u can spend virtually no time with them without someone standing over ur shoulder as a chaperone.
good luck. just be careful and patient. love is not sitting on every corner but i am sure it is out there.
you have options
