Hi,
I've been in a happy, healthy relationship for over a year and my boyfriend has been struggling the past few days with anxiety due to lockdown, he has been finding it hard to work from home etc and has started online counselling for anxiety but two days ago he accused me of cheating with a friend of mine who has previously declared feelings for me but I wasn't interested. I have stayed friends with this person and my boyfriend never showed an issue but two days ago he accused me of cheating, says I get private about my phone but I explained to him I only do that when talking a friend when they are looking for advice or talking about something private.
I've also been out of the house a lot more than him as I've been helping family in lockdown so I've been out and about a lot more over the past few weeks. I always gave him the option to go with me.
The friend he is suspicious of has been hanging out recently as we moved house and he came over to take some furniture for his apartment, but again I involved my boyfriend in this and never hid anything. Two days ago he started to freak out, and when I reassured him he then did it again yesterday. I said he could talk to my friends too or see messages but he said my friends could just cover for me. I'm really not sure what to do, is this just insecurity? I'm reassuring him constantly but am now very tired doing so and am wondering about applying tough love. It really makes me worried for a future together xx
