I'm 17 and she's 16. we've been in a relationship for 3 months now and we see eachother on saturdays (she lives an hour and fifteen minutes away by public transport). I don't have any friends really... we don't look on eachother's phones as we trust eachother like America trusts America. when we're together in person we mostly cuddle, go for walks, do fun things downtown and have intimate moments. that is basically all in short

My girlfriend invited me in her friendgroup in the beginning of our relationship. However, when I see her voice messaging and sending video's and pictures more in that friendgroup and spending little attention to me I get jealous. Recently I have learned this happens to her too. Any advice or notes? (we both have conditions like ADHD and autism spectrum disorder)
