But whenever she went out it was always a friend. Never any details or anything. This bugged me because deep down I'd just rather know if atleast it was a guy or girl. I didn't really care if it was a guy but if she atleast gave me a name or something then atleast I'd know she's being somewhat honest and giving me some info.

This isn't suspicious behaviour. If I was going out with friends while in a relationship, I'd tell my bf by saying "I'm going out with friends" or "I went out with some friends last night, pretty good time". He might ask 'who were they' and I'd say "work people" or "x and y" if it's a smaller group. And vice versa when he went out. But I wouldn't send a text saying "I'm seeing two female friends today, patricia and alice" or whatever. Because I expect my bf to trust that I am not cheating on him - and vice versa! I would hate to have to explicitly say who I am with every time I do something, especially at the beginning of a relationship. It's a bit different if you've been together for a while and live together, because you'd expect to know where your partner is (because you live together, NOT because you have anxiety about them cheating on you!). If I was your girl, I wouldn't hang around.

It seems you know your insecurities are unfounded and a big negative impact. I'm not a psychologist so I can't give you advice on that.

I just want to impress that if you put in rules like having to text who you are with and their gender all the time, you are putting the burden of your anxiety onto your partner.

You also need to remember that your current partner had nothing to do with whatever hangups you have. You are punishing her and she is innocent.

So the only thing I'd say is that while you sort yourself out with a professional, keep yourself from blaming and punishing your innocent partner.
