<human>: Condense the text into a few key points

Have been together for that time only I'm one who thought i would never date again. She is a single mom with a 2 y/O who she has no contact with his father. I have become part of both their lives with full immersion. 

We moved in after 2 months both our leases ended and we both wanted to be closer to each other and work. 

Things where perfect but we never discussed issue we both have like her anger problems and my constant need for sex and affection. We had no problems but now argue and fight over anything since we thinks all I want is sex and I think she might just need me for support. We are happy and have an amazing time together and with her kid who is my little man. But I am made to feel guilty for wanting her to make time for me and our sex life as well as privacy. 

We now say things we don't mean and are different if something bothers me I say so for her she gets mad shits me out which in turn makes me press harder turning to anger for her ignoring me. Then she turns it I to me being unhappy and a psycho for getting upset. 

Lately this has turned me into an insecure person about my sexuality and her attraction to me. I feel like I am being cheated of a healthy de life which she probably had with her ex partners as well as her kids biological dad who was a mistake and only slept to ether a few times.
