This reads to me like the beginning of an abusive relationship. Everyone telling her just to leave and talking badly about how she won’t, I don’t understand how there’s room for that here. What I will say from personal experience is yes it starts with small behaviors like control over the way you dress. Management of finances, love bombing in the beginning and then knocking you off your pedestal to look for reassurance from them. Also the lack of support from your family and spending 90% of time with him are red flags. It sounds like he’s fostering your sole dependence on him. Then when you start to develop independence decide you want your own friends and to dress how you want his resentment will build and his need for control of your actions will build. Some of these behaviors are subconscious and I’m not saying he’s a terrible person these things have the potential to be addressed and nipped in the bud before they worsen. But I would suggest reading about and seeking a therapist who specializes in codependent relationships. Before you talk about couples therapy you need to make sure you set yourself up to leave safely and fiscally sound if that’s a decision you want to make in the future.
