I'd like to start by saying I love my dp. We have been together 12 years and have lovely dc. We've had a lot of stresses through the years with poor health and money worries but we mostly get on and are usually very happy together.
The problem is I've started to have strong feelings towards my colleague. We work together 4 days a week and I'm finding I'm looking forward to those 4 days with him rather than my days off with dp. I feel really shit about it as I love the family we have together.
The man in question is very flirtatious towards me and always complimenting me on how I look and has become very touchy when we are talking to each other. An example is I banged my elbow on the desk so he began to rub my arm! Usually if anyone touched me I'd pull away but this time I didn't. It's been other times too.
Im wondering if I should tell my dp what's happening or if I should just try and back off from said colleague and hope he backs off too. I'm worried if dp saw the way he was acting towards me he would think something was going on behind his back but it's not.
