Alhamdulillah, I Embraced Islam Last Friday

As-salamu alaykum, I'm 19 and I decided to embrace Islam last Friday. Before that, I honestly didn’t know much about it and thought Muslims worship the Ka’bah 😂. I was an atheist all my life, thinking religion had no purpose and that Allah didn’t exist. I had a close Muslim friend, but I never really understood what she believed in-just assumed it was about the Ka’bah. One day when we were out, I asked her about her faith. She told me she believes in Allah, the Creator of the universe, and that she follows all the prophets including Prophet Muhammad (peace be upon him). I asked her more questions, like what exactly she means by God. She then showed me verses from the Quran, like Surah Al-Ikhlas, explaining that there is only one Allah, who was not born, has no beginning, doesn’t need anyone, and nothing is like Him. I told her that was interesting and that I hadn’t realized she believed that. But I still wasn’t sure if Allah really existed. She asked me, "Who made your sweater?" It was a simple question and I said, "I don’t know, maybe a company." She replied, "If your sweater couldn’t come into existence by itself, then how could the universe or people?" That really made me think on my way home. Her simple question kept me awake all night. Maybe I didn’t come into existence by myself after all. I tried to ignore it for a few weeks but kept thinking about what she said. Eventually, I did some online research and attended some events. I asked if I could visit her mosque and see how Muslims pray. She agreed and picked me up one day. Inside, it was very different from what I imagined. I saw groups of Muslims praying together, all standing side by side, including the sisters. It was a Friday prayer and there was a lecture about death and how this world is temporary. I felt like they were speaking directly to me, as if they knew I was there. After the prayer, I went home wondering what this all meant. Then, on Friday, September 26, alhamdulillah, I took my shahadah at the mosque. I felt so happy and relieved, like a new person. I want to be honest-I'm a woman in a relationship with my wife for 3 years, and I care about her a lot. I’m still learning about Islam and I’ve heard that same-sex relationships are not allowed. I’m unsure what the Islamic perspective is exactly, so if someone could kindly advise me on this, I’d really appreciate it as I continue my journey.
