Hope I’m not being controlling but my boyfriend has a good friend who he seems to spend a huge amount of time texting when we are not together . They are friends for years and it’s just chatting and funny’s that they send to eachother but they could have up to 30 texts an evening from what I can see. Nothing untoward or dodgy but very sensitive chats sometimes .she is a lady btw. He doesn’t really text her when we are together. Although, he was away for a weekend abroad recently and I can see that they were texting each day. They work together.
