Okay so I've recently just moved in with my boyfriend before this we use to have sex every single day he's only just turned 23 and I'm 19 he's suddenly just lost interest in me and every time I ask him why he doesn't want to he just says that he is tired yet his routine hasn't changed?

I'm beginning to think he's cheating on me I've mentioned it as a joke but he went mad and said how could he possibly have time to do that but other days he would joke about cheating on me. Since we have moved in he just pretends that I'm not there and the only time he asks me to do stuff is to make him tea or something any ideas of what could be happening or what I should do I'm quite a shy girl and I've never think of myself as attractive but this is making me feel so much worse

Who knows, but him? He could be the kind of guy who likes the chase, not knowing what you might be doing when he's not around, and it turned him on. Now he's 'got' you and he's lost interest. It could be he isn't used to living with someone, especially a woman. It could be he's modeling himself after his parents now, who barely speak except when his dad asks for tea.
I'd tell him you were happier living apart! I realize moving is a huge hassle, but I'd at least start looking into it. It's much worse to have to beg for the smallest crumb of attention and affection.

Lack of sex is generally a symptom of problems in other areas of the relationship, and if you take it personally, you will never find out what it is. How long had you been together before moving in? Do you both work?

Lust fades, love grows, it just takes a steady dose of honest communications from you both.

Are you in a social rut?

Yea we both work I have two part time jobs and he works full time we've only moved in together a few weeks ago we have been together for just over two years

Expect positive changes to take time as you both get adjusted to your new arrangements. Takes some time.

Thank you :) il keep you's updated to see if there are any changes to his attitude :)

It definitely takes some adjusting to the change of scenery. Give him some time, I would highly recommend for you to ask him what is going on though, only he knows.

It sounds like the "new" has worn off in your relationship. Mix it up. Make him WANT you.

We always think the worst. We always let our minds wander.

Be careful. Good luck.
