So Ive been dating a younger guy for a 6 months now, things have been going pretty good. I'm 23 and he's 18. He's cute, sweet, funny and loyal and I don't think he'd ever cheat on me. We both still chat online and on apps with other guys not so much sexually as moreso we have made friends on these apps. However lately I've been having some issues with not so much trust as just an uneasiness and feeling quite insecure. We currently are only able to see each other every few weeks due to university and school and work commitments and him not being out to his parents as well (he lives at home). I have asked him straight out if he is having second thoughts etc and he's adamant he isn't. They've come to the forefront of late because we have had a bit of a lull in our relationship, we aren't talking as much as we used to and he seems to be distracted alot. I just want to make sure it's me and not him.
What are people's thoughts.
