I've been seeing a man for a while and all going great. We often stay over at each other's houses, get on well with each other's kids (all teenagers), have been away together and do variety of things together. He's recently asked me if I think we will move in together. Although I enjoy having him stay over, i find it difficult to think about a man moving in. I'm not entirely sure why. I trust him and don't have any major misgivings. Anyone else had similar feelings?
