The approach to finding friends is a delicate one, first I would urge you to consider a possible change of mindset and your approach and beleive this may be a good first step for you. Ask the Holy Spirit to open your heart to those around you! Sure, you can always try another parish, however, at least for now you are in THIS parish. Jesus has known from all eternity that you would be here and would be having this struggle. Ask him to open your eyes to the possible friends around you that you may be blind to because they came across as pious or humor-less. The overly pious men you meet might indeed be very nice, God has not blessed everyone with a witty sense of humor, some people are not as relaxed. Also you have been invited to events, that is a wonderful sign! Even if you don’t find friendship at your parish and wind up going elsewhere, at least see the people there through a lens of kindness, it sounds like they have tried to befriend you just that they don’t have the right chemistry for you which is not a “lack of honest Catholic dialogue” as your post suggests but merely how life is sometimes.
With all Christian charity, you seem to be seeking friends for yourself and for other men to help you deal with your problems. Wanting friends is natural but if you are able to open your heart where you are seeking also to be a friend and seeking how you can support others I think many doors will open for you. Forgive me if I am off-base, I only have your post to go by and that is how you came across to me. Clearly you are a good and religious man, but in the area of friendship you are struggling. You may be right in that all the men you meet are not “right” for you, however it is also possible you are sizing them up as you meet them and may be overly critical at times.
I will share my experience to explain why I feel this way. I knew a woman who after she met me wanted to hang out because she was seeking good Catholic female friends, not a bad thing actually but her approach felt funny to me. When we got together a few times she talked a lot about herself and her faith. She asked if she could meet my other friends because “she needed more friends.” I felt very odd around her, I never felt as if she really liked me or was interested in getting to know me. I don’t bear her any ill will, she was not a bad person pe-se but her approach to friendship seemed she was seeking a support group for herself rather then a genuine relationship. I know that still to this day she struggles with friendships and it is unfortunate. I pray for her because she is a lovely soul but in this area she is still struggling, I beleive because she is seeking friends for herself which is not (in my opinion) the best approach. Open your heart, Christ knows exactly what you need.
God bless you on your journey and please be assured of my prayers.
