Have done this before, was outside his house and waited for sometime but didn't see anything. We have had conversations about fidelity etc and he was pretty clear he does want me only and me him. Due to a traumatic event where a guy a couple of years ago, posed as single while he was married, it's impossible for me to trust 100% anyone I'm romantically involved with. The past few weeks I noticed a change in behaviour in him. He did seem to not initiate contact with me and not really asking to meet me. I brought the issue up with him and he said he has some issues with work recently and responsibilities like for example he argued with his boss as he was changed area and with his son. We've seen each others 2 years now but we are not what I would say full on committed, we are exclusive though and a steady presence in each others lives. I am thinking to spy on him outside his flat. I'm just wondering if it's better outside, behind a large Bush, or inside the flat entrance, I can hide either upstairs so I view his flat from above, or downstairs so I can view the flat from below but I think it may prove risky if I bump into a neighbour. Any thoughts
