rant/advice

Okay so I feel absolutely terrible. My husband and I have been together for 2 years married for 2 months. We have a 4 and half month old. Everything should be perfect. Well I like men and women. I have slept with women while he watch and have included him. Well I went on tinder intentionally to find someone for us as a surprise. well I got a little carried away and was more talking to them for my own pleasure. This morning when he got home from work he saw on my phone that I had a new match. him not knowing I had a tinder went through it. he was not very happy needless to say. I don't know why I did this. I'm very happy with him. I not sure if I'm going manic (I have bipolar and known to do this type of thing when manic) but I don't really feel that off and I've been taking my meds. or am I just fucked up person that has no self control?
