i have been with my partner for over a year, things were good until 3 weeks ago when he just started getting short/snappy out of nowhere. We had a big argument as he kept just finding the smallest things to moan about (which he hasn’t done until now) and we didn’t see each other for around a week. He went out on Friday with his friends after telling me he wasn’t sure about us anymore so I left him to it, he seemed very adamant that he didn’t actually want to be with me anymore. The next day he called me and apologised, said he was sorry and loves me. This was 3 weeks ago and since then he’s been nothing but nice… but what’s making me paranoid is a couple of things, the first being that when we first got into a relationship we both did std tests and was both clear, I made sure we did this. He still had a test at his house, in his drawer and hasn’t been touched in all of that time. Within in the last three weeks it’s gone. We haven’t slept together either since we had the argument which is quite unusual. He has actually made excuses as to why he can’t have sex even though I’ve expressed some frustration. He has also booked us a holiday to the place he knows I’ve always wanted to go. I can’t shake the feeling he’s done something but do I confront him?
