hello all!

Looking for some advice. I'm new to the group. Basically, my girlfriend and I started dating in November after being friends for a while. We met in the Pride band in our city. Her family is super cool and she is very close with them. Her Parents though....well...her Dad is the youth minister of an ethiopian church and her Mom is the children's minister. Her Mom actually joined the Pride band, as she wanted to play flute again, however she has already said that she can't play in the pride concert as the church does not support the "gay lifestyle"....aka every lgbtqia+ person is going to hell....unless they are with the opposite sex. Her Mom is super nice to me though and we have played games together and such. Her Dad is cool too up to a point. He is def not accepting of her being a lesbian. He is maybe going to come see this next concert of ours (big step for him) and we get along great as human beings. However, any time my gf and I hold hands or put an arm around each other, or even look at each other in a loving way, then he gets super affected by it and shuts down and gets all mopey. It's a weird situation for me....I'm newly out as of last year (this is not my first lesbian relationship) and she has been out for 10 years. She is extremely important to me though and I already know that I want her to be in my life for a very very long time, so I want to handle this in the best way possible. She is going car shopping this weekend and I am going to go with her. She was telling her parents about it and her Dad also wants to go (knowing that I will be there). I talked with her about my reservations with his reactions and she understood. I know that I am going to go though because I want to be a part of her life and I don't want to let someone else affect my time with her. Has anyone been in a similiar situation and how did yall handle it? Any advice yall could give me? Some other info: they didn't talk for 2 years when my gf came out and now they have built a relationship together again. My gf has also not dated anyone in 3 years because it was easier for her and her family relationship to be single. She has assured me that no matter how her parents react about our relationship or in regards to me, that it will not change her want to be around me or with me. Gratitude in advance for any advice!
